Hi ! I was wondering if someone else has noticed a similar behavior: I wrote an URL-rewrite script with PHP as explained at <http://wiki.squid-cache.org/ConfigExamples/PhpRedirectors>. The script was running without complains under Squid 2.7.Stable9 and Ubuntu 9.04, then I upgraded Ubuntu to 10.04 and warning messages started to show up: 2010/05/15 16:48:28| WARNING: url_rewriter #XX (FD XX) exited <---- (repeat n-times) 2010/05/15 16:48:28| Too few url_rewriter processes are running 2010/05/15 16:48:28| Starting new helpers Things I've tried to solve the issue without success: - Simplified the PHP script to the minimum (finally just using the wiki's example). - A clean installation of Ubuntu 10.04. - Downgraded PHP package from 5.3 to 5.2. - Recompiled Squid (just in case). Perl scripts are not afected, so I rewrited/transalted the script. The service is up again but a big question mark was left over my head. I know it's not a Squid's issue per se, but at least the wiki may need to be updated before other people get stuck at this point... Thanks for reading. ----------- squid.conf: ----------- url_rewrite_program /etc/squid/phpredir url_rewrite_children 32 --------- phpredir: --------- #!/usr/bin/php <?php $temp = array(); while ( $input = fgets(STDIN) ) { $temp = split(' ', $input); $output = $temp[0] .
