[squid-users] socket failure: (24) Too many open files

[Eliezer Croitoru]

I recommend Squid upgrade if possible due to couple bugs as something..
Try to bump the server to 32k open file descriptors and see what 
happens.
Depends on the load on the server it might need at peek times more then 
8k.
The cache manage info page should give you couple technical details on 
the status of the service.
It can also give some statistics which might shed some light on the 
scenario.
Others might be able to give you some more detail on the relevant cache 
manager pages.
