Re: mod_fcgid: I see... I guess I'll modify mod_fcgid myself for that setup. That doesn't explain the mod_fastcgi problems though. I thought it might be something with my setup so I rebuilt it from scratch... might have had some old crap left behind. I don't get 500 errors with PHP 5.2.3 + mod_fastcgi 2.4.2 + Apache 1.3.37 anymore, so it does look fixed in 5.2.3... but I get another strange problem: doing a graceful restart shortens the sleep time to zero. i.e. <?php $a = time(); sleep(30); echo time()-$a; ?> Going to this page then doing a graceful after 5 seconds would give "5" instead of the expected "30". php5.fcgi== #!/bin/sh export PHP_FCGI_CHILDREN=4 exec /opt/php5/bin/php-cgi $* For the record, PHP 4.4.7 dies with a 500 error, but that's not a big problem for us... Could the OP perhaps provide us some info on what versions of Apache and mod_fastcgi/mod_fcgid so we can try replicating it? Previous Comments: ------------------------------------------------------------------------ [2007-06-13 17:40:12] [EMAIL PROTECTED] PHP/fastcgi catches SIGTERM and always does graceful shutdown, however mod_fcgid sends SIGTERM then waits for one second and sends SIGKILL if PHP process isn't exited. So this is not a PHP issue. ------------------------------------------------------------------------ [2007-06-12 19:31:57] severn-php at xephris dot net >From the looks of the changelog, Bug #36158 was fixed in 5.1.3 I just tried that with mod_fcgid 2.1 and Apache 2.2.4 on x64 Linux and it too "died". mod_fcgid sends SIGTERM to the PHP process which dies returning a blank page. I also tried it with mod_fastcgi 2.4.2 and Apache 1.3.37, that died with the 500 error. I've also tried PHP 5.1.6 and 5.2.3, same issue. So... it looks to me like the bug was never actually fixed... (not in 5.x at least). I get the same behaviour with 4.4.7 (blank screen with mod_fcgid, 500 error with mod_fastcgi) ------------------------------------------------------------------------ [2007-06-05 07:58:15] jonepet at dcvhost dot no As of the close/last comment of Bug #36158 it was working at that time. I don't know if it really did, or if there was any releases with this fix. I didn't meant "previous version" but "earlier version", in the original description, referring to the last comment of Bug #36158. ------------------------------------------------------------------------ [2007-06-05 07:34:58] [EMAIL PROTECTED] In what PHP version did it work? ------------------------------------------------------------------------ [2007-06-04 23:06:35] jonepet at dcvhost dot no Description: ------------ This is a duplicate of older closed Bug #36158. Solved in previous version, but broken again in newer (because of replaced lib?). The FastCGI module in PHP does not handle graceful/SIGTERM shutdown/reload correctly. When sending a graceful reload to Apache, all running PHP processes dies, and Apache return "500 Internal Server Error" to waiting HTTP clients. Reproduce code: --------------- <?php sleep(10); echo "Done"; ?> Open in a web browser and then do an apache2ctl graceful on the server. Expected result: ---------------- "Done" should be printed to the web browser after 10 seconds. Actual result: -------------- "Internal Server Error" to browser and "premature end of script headers" to log file. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=41593&edit=1
