There are probably 2 issues here. First I believe squid detects the number
of file descriptors available at compile time and compiles that in
as a maximum limit.

Secondly, if ordinary users use the "H" flag when changing limits, they
can't increase the limit above that level again during that session. Run
umlimit -n to see what the setting really is.
