Are you sure? It may be a runtime limitation; please check that
there's a 'ulimit -n 8192' line in the squid startup script (replace
8192 with your desired limit).

the debian package may have different configure options; if you miss
some configuration option your configuration file may be incompatible
with your new binary.
you may want to run 'squid -v' to check that your new configure
options are compatible with the previous ones.

You may also want to keep your old binary around, to be able to roll
back in case of problems.
