Error 49, socket problem?

[Stephane Raimbault]

I have some busy boxes part of a cluster which seems to occassionaly get an 
Error 49 on various network based applications at the same time.

Here is from an apache proxy log

[Fri Oct 08 11:26:45 2004] [error] (49)Can't assign requested address: 
proxy: HTTP: attempt to connect to 127.0.0.1:81 (127.0.0.1) failed
[Fri Oct 08 11:26:45 2004] [error] (49)Can't assign requested address:

Various other things at the same time give a similar error.  Am I running 
out of sockets on the system?  What is the best way to diagnose this 
problem.  It seems pretty intermitent, however it seems to occur when the 
boxes are at some of the busiest moments in it's day.

Thanks,
Stephane.
