Hi,

I have been posting on and off about a network request to host error when connection from Windows to Classic server running on Linux.

Finally we tried this configuration

Linux Server - 2 NIC Cards.
Windows 2000 Desktop connecting to the server on one of the NIC cards directly with a Patch cord which has some wires switched around to make direct connection.
Other NIC card from Linux server connecting to switch.

Still getting occasionally. (Maybe once or twice a day But when it happens this problem goes on for around 10 min)
ISC ERROR MESSAGE:
Unable to complete network request to host "192.168.1.202".
Failed to establish a connection.
The system could not find the environment
option that was entered.

(Note this environment option portion of the message did not come before we did this NIC to NIC connection)

During this time other (single threaded)clients are able to connect through the switch.

Only this multi thread client which is connecting NIC TO NIC is giving a problem

This is
$00551C56 PlasmaServer.exe IB_Session 1107 TIB_SessionBase.HandleException
$004FDFEE PlasmaServer.exe IB_Components 1859 TIB_Connection.API_Connect
$004FC517 PlasmaServer.exe IB_Components 1159 TIB_Connection.SysConnect
$004F9EC1 PlasmaServer.exe IB_Components 295 TIB_Connection.Connect
$00749C5D PlasmaServer.exe JLDBConnectionPool 56 TJL_DBConnectionPool.GetConnection
$0074AE2D PlasmaServer.exe Downloadmultifrm 331 TfrmMultiDownload.downLoadNext

Any ideas. The client is about to cancel my contract.

I have tried every possible thing under the sun to try to isolate this problem.
Is there some tuning I have to do either in ibconfig or on the linux system

Both of these have been left more or less at the default.
Could it be that the server is running out of memory and thus unable to create a new process on the server ??
It is a 512 MB RAM system. Performance etc. seems to be fine otherwise.
