Bug #54098 [NEW]: Overly high defaults in config

From: Operating system: Linux PHP version: trunk-SVN-2011-02-25 (SVN) Package: FPM related Bug Type: Bug Bug description:Overly high defaults in config Description: ------------ The default setting in the pool sets pm.max_children to 50, which with php's upped default memory_limit of 128Mb makes many moderately equipped machines to crash from out-of-memory. The settings combined makes it possible to consume 6GB of memory in a bad scenario. Since I suspect many a server nowadays are 1Gb (or even 512Mb) VPS's running on the different clouds out there, the settings are grossly excessive. I reported a bug against Ubuntu at first, but I think this is really the right place for it. https://bugs.launchpad.net/ubuntu/+source/php5/+bug/723480 pm.max_children should be more like 6 initially, with an explanation to increase the number if memory permits. Ether that or the default memory_limit should be lowered. I have read posts about running VPS where operators have to reboot every so often, and I think it *might* have to do with this problem, since I'm sure nginx+php+php-fpm is getting very popular as a stack. Expected result: ---------------- Snappy happy server. Actual result: -------------- Server get sad, wrinkles, get dementia, finally get a stroke and dies. Takes as long time as it took my mother but in computer-years. -- Edit bug report at http://bugs.php.net/bug.php?id=54098&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=54098&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=54098&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=54098&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=54098&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=54098&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=54098&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=54098&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=54098&r=needscript Try newer version: http://bugs.php.net/fix.php?id=54098&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=54098&r=support Expected behavior: http://bugs.php.net/fix.php?id=54098&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=54098&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=54098&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=54098&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=54098&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=54098&r=dst IIS Stability: http://bugs.php.net/fix.php?id=54098&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=54098&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=54098&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=54098&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=54098&r=mysqlcfg
