[squid-users] All url_rewriter processes are busy x Too many open files

Testing Squid/SquidGuard with thousands of users, the cache.log shows
the following messages:

2008/04/01 15:19:16| WARNING: All url_rewriter processes are busy.
2008/04/01 15:19:16| WARNING: up to 2730 pending requests queued
2008/04/01 15:19:16| Consider increasing the number of url_rewriter
processes to at least 3552 in your config file.

The server is a HP DL360G5 (2x Xeon Dual 1.6 GHz, RAM 8 GB, HP Smart
Array - RAID 1).

Is there any way to increase SQUID_MAXFD from 8192 to 65536, so I can
try using the sugested number of url_rewriter processes?

With SQUID_MAXFD=8192 I got lots of "comm_open: socket failure: (24)
Too many open files" if url_rewriter is set higher than 200 (roughly).

Thanks for any help,
Marcio.
