Connection reset by peer

[Luv Bhatia]

Our application has a screen for customer registration/modification which is accessed by 45-50 users simultaneously.
while accessing those screens the following error message comes and it hangs the web Server.
The web server then needs to be restarted.

[05/Apr/2005:12:53:51] failure ( 820): Error accepting connection -5961, oserr=997 (Connection reset by peer)

Is it related to the number of users accessing the
Server concurrently??

I'm using:
Sun One Web Server 6.0 SP2
jdk 1.4.1_02

Any help would be really appreciated...
