The behavior we see is a steady increase in open files (lsof -p
There are two servers .. servera and serverb. Same config. So we thought. There where some kernel changes made to sync the systems up but that did not change the issue.
I checked ndd settings and can not find anyting related to socks.
Am I missing something?
Solved! Go to Solution.

Re: Sockets ..
But here is the kicker .. it is set to 2048 on both servers. But one still have the issue with the sockets and one doesnt.
same hardware, same build image, same kernel parameters.

Re: Sockets ..
Our application is leaking file descriptors.
(sockets are file descriptors just as squares are rectangles)
The suggestion to call shutdown() is probably on the right track, but insufficient - shutdown() does not actually free the file descriptor. You have to call close() for that.
So, some tusc'ing of the server application to see what system calls it is making, and if it is properly responding to say read returns of zero (indicating client close) would seem to be inorder.
If the client's aren't closing on their own accord then perhaps the server application requires a means to cull older connections on its own.
