Depends on your OS.

The default is 1024.

YEs, but even more so between file descriptors and CPU usage.

Mainly when CPU starts becoming a bottleneck.

Quite likely you have some other problem with the filedescriptor problem
only being a side effect. 8K filedescriptors is well more than plenty for
any Squid I have seen.

How many clients do you have on this proxy?

Try

   half_closed_clients off
   quick_abort_min 0
   quick_abort_max 0
   pipeline_prefetch off

And what cache_dir type are you using, on how many drives?

Is there any swap activity on your server?
