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. 2008/04/01 15:19:34| WARNING!

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.
