Short answer
Error 10054 is not a Baan-specific code: it is the Windows Sockets error WSAECONNRESET, meaning the other side of the connection (the bshell on the BSE server or something in between) closed or dropped the connection abruptly. Fix it by finding out who closed the socket: the bshell crashed or was killed, a firewall or load balancer cut an idle connection, or the server ran out of resources. Error 206 is a separate database or file level code that you read from the log, not guess.
Applies to: Baan IV, Baan 5, Infor ERP LN 6.1 and Infor LN 10.x with the BW client or Worktop; Windows and UNIX/Linux BSE servers. Exact message text varies by version.
How to fix Baan error 10054
- 1Note when it happens: at login, after idle time, or while a heavy session runs. Idle-time drops point to firewalls or load balancers; mid-session drops point to the bshell dying.
- 2On the BSE server, check the bshell log files in the BSE tmp directory (log.bshell and the per-session logs) for a crash, core dump or error at the same timestamp.
- 3Check that the bshell process for that user still existed at the time. If the server killed it (out of memory, ulimit, an admin killing a hung process), the client sees a reset.
- 4Check firewalls, VPN and any load balancer between client and server for an idle timeout shorter than your users' idle time. Raise the timeout or enable TCP keepalive.
- 5Test from the same client with a short session, then a long idle session, to separate network faults from server faults.
- 6Review server resources: memory, swap, process limits and the maximum number of concurrent bshell processes allowed by your license or configuration.
- 7If one session or report always triggers it, run that session with debugging or in a separate test user to find the crashing code, then raise it with the owner of the customization or with Infor support.
- 8For error 206, copy the exact message and the session code from the screen and the log, then look up the number in the message definitions for your version before changing anything.
Why 10054 appears in a Baan environment
Baan and LN clients talk to a server-side process called the bshell. The client opens a TCP connection, the server starts a bshell for that user, and every screen action is a message over that connection. Error 10054 is simply the operating system telling the client that the peer reset the connection. It does not say why, so you must look at the server side and the network path.
The three usual suspects are: the bshell crashed (bad customization, memory corruption, a DLL or shared library problem), the network device between the two ended the connection (idle timeout, packet inspection, a VPN reconnect), or the server killed the process because of a resource limit. Almost every case falls in one of these buckets.
Telling a network drop from a bshell crash
If the problem is network-related, many users on the same site or link are affected at the same time, and the bshell processes are still alive on the server afterwards (they linger until cleaned up). If the bshell crashed, only the session that crashed is affected, and you will find an abnormal termination in the bshell log or an operating system core file.
A quick check is to list the user's bshell processes before and after the error. If the process is gone, look at the server. If it is still there and the client lost it, look at the network. Packet captures on both ends settle disputes between the network team and the application team.
# UNIX/Linux: is the user's bshell still alive? ps -ef | grep bshell | grep <username> # Windows: check Task Manager or tasklist | findstr /i bshell
Error 206 in Baan
Error 206 is reported by the database or file layer of BSE, not by the network. Numeric Baan error codes are looked up in the message definitions of the version you run, and the meaning is shown in the log together with the table or file involved. Do not apply a fix you read on a forum for a different version without confirming the text.
In practice, errors in this range appear when a session touches a table or file that is missing, not reachable or not in the expected state, for example after a restore, a partial conversion or a runtime data dictionary that was not rebuilt. Check the table name in the log, confirm it exists in the database, and confirm the runtime data dictionary and table definitions are current for the package VRC in use.
Prevention for older Baan servers
Old Baan IV and 5 installations often run on aging hardware, with bshells that were never recompiled, and with firewalls added years later. Keep an inventory of what sits in the connection path, document the idle timeouts, and keep a baseline of bshell memory use so that growth is visible before it causes crashes.
If the system is being kept alive only for a few reports or for audit access, the cheaper long-term answer is often to stop depending on the client connection at all and expose read-only answers through another route. That is a migration and access decision, not an error fix, and our Baan IV migration checklist covers it.

Common pitfalls
- !Treating 10054 as a Baan bug. It is a generic Windows socket reset and the root cause is on the other end of the connection.
- !Raising client timeouts only. If the server killed the bshell, no client setting will help.
- !Ignoring the timestamp. Without the exact time you cannot match the client error to the server log line.
- !Searching a forum for error 206 and applying a fix written for another version or database driver.
- !Restarting the whole BSE for one user's problem and losing the evidence in the logs.
How an ERP-grounded AI assistant handles this
A private assistant grounded in your log files and your own incident history can match a 10054 timestamp to the bshell crash entry, list which users and sessions fail most, and suggest the bucket (network, crash or resources) before an admin opens a log. It reads logs and tickets; it does not change the server. For legacy Baan sites, Netray builds this on-prem so logs never leave the network.
Frequently asked questions
What does Baan error 10054 mean?
It is the Windows Sockets error WSAECONNRESET: the connection was reset by the other side. In Baan or LN that usually means the bshell on the server ended, or a network device between client and server dropped the connection. It is a symptom, not a cause, so check the server logs and network timeouts.
Is error 10054 caused by a license problem?
Rarely. License and session limit problems normally show their own message when the session starts. A reset in the middle of work points to a crash, a resource limit or a network device. Check license messages only if the failure happens at login and only for some users.
Why does it happen after the user is idle?
Firewalls, VPN gateways and load balancers often drop idle TCP connections after a set time. When the user returns and clicks, the next send is answered with a reset. Raise the idle timeout or enable TCP keepalive on client and server to stop it.
How do I find out what Baan error 206 means?
Read the full message and the table or file named in the bshell log, then look the number up in the message definitions of your Baan or LN version. The meaning depends on the layer and version, so confirm before you change the database or data dictionary.

Infor LN bshell Process Stuck at 100% CPU: How to Diagnose and Fix It
A bshell process pinned at 100% CPU on the Infor LN application server almost always means one session is stuck in a 4GL loop, scanning an unindexed table, or waiting on a database lock. End the session from the Sessions Monitor first, then kill the OS process only if that fails, and check for a blocking database transaction before assuming it is a bug.

How-toBaan IV to Infor LN migration checklist
Moving from Baan IV to Infor LN is a re-implementation, not an in-place upgrade, because the two products differ in data model, session technology and, for LN Enterprise Edition, the underlying runtime. The checklist centers on inventorying customizations, converting master data, rebuilding logic rather than porting it, and running a real parallel test before cutover.
AdvancedHow to diagnose and fix a slow Infor LN session
A slow Infor LN session is usually caused by an unindexed or overly broad database query, unarchived data bloating a transaction table, or resource pressure on the Java application tier, and occasionally by a recently added custom DAL2 handler. The fix starts with isolating which tier the delay is actually in rather than guessing at a solution.
Error fixInfor LN Not Authorized to Run This Session: How to Fix It
Infor LN refuses to open a session with a not authorized message when the logged-in user's assigned role does not include that session, or when the session is blocked for the company they are logged into. Grant the session through Common > Authorization Management > Roles, or check the user's role and company context, and the session opens on retry. In most cases this is a permissions configuration issue, not a bug.

Infor LN throws a DAL, or table, out of sync error, or simply drops a new custom field silently, when a table's dictionary definition is changed but the generated DAL and dependent forms are not regenerated afterward. Running the standard sequence, table compile, DAL generation, then session/form compile, in Tools > Development after every dictionary change resolves it. Skipping any one of the three steps is what causes the mismatch.
