Hi,

I set my /etc/security/limit.conf:
* soft nofile 655360
* hard nofile 655360

so user squid also has limit in 655360:
# cat /proc/SQUIDPID/limits
Limit Soft Limit Hard Limit Units
Max cpu time unlimited unlimited seconds
Max file size unlimited unlimited bytes
Max data size unlimited unlimited bytes
Max stack size 10485760 unlimited bytes
Max core file size unlimited unlimited bytes
Max resident set unlimited unlimited bytes
Max processes 257742 257742 processes
Max open files 655360 655360 files
Max locked memory 65536 65536 bytes
Max address space unlimited unlimited bytes
Max file locks unlimited unlimited locks
Max pending signals 257742 257742 signals
Max msgqueue size 819200 819200 bytes
Max nice priority 0 0
Max realtime priority 0 0
Max realtime timeout unlimited unlimited us

and my fd.file-max is 655360 too:
# cat /proc/sys/fs/file-max
655360
