Article #25340: All connections lost at once with error 10054

Problem:
All connections lost at once with error 10054 in interbase.log.  It can 
happen with both Service pack 2 & 3 for NT 4.0.  InterBase Server is 
still running on the server.  


Solution:
Error 10054 is a winsock error for connection reset.  You can find the 
list of winsock errors in the winsock.h file.

Since the InterBase Server is up and running at the time of the problem, 
it's an indication that it's not an InterBase issue but rather a network 
issue.  Check the following:

 *  At the time of the problem, what's the traffic load?  Check for 
    traffic loads that can flood the network. Is there anything scheduled 
    to flood the network at certain time?

 *  Check for network hardware problems such as bad switch, router, 
     hub, etc.

*   Another possible scenario involves having more than one protocol
    bound to the same network card. In one case a customer had TCP/IP,
    IPX/SPX, and RIP for IPX bound to the same ethernet card. When he 
    unbound IPX/SPX and RIP for IPX from the card, the errors disappeared.
