Hi, When my cache is busy, if I issue a SQUID -K RECONFIGURE then Squid very often crashes with: FATAL: Too many queued url_rewriter requests (54 on 12) This seems only to happen when the cache is busy. Once the FATAL has occurred, Squid needs to be restarted manually. Changing the number of url_rewriters does not seem to make any difference. Also, issuing the reconfigure when the cache is not being used or is under light load is never a problem. Is the problem with Squid, or the re-writer? I think it may be an issue with how Squid handles incoming requests during the reconfigure (and the shutdown and restart of its url_rewriter helpers). I am using SquidGuard 1.3 as the url_rewriter. All DBs are in binary format, so startup time is not long. I am using Squid 2.6 STABLE 18 with the select loop. Thanks for any suggestions or thoughts you may have, Stephen
