From: map at infinitum dot ch Operating system: FreeBSD 5.3 stable PHP version: 5.0.3 PHP Bug Type: Session related Bug description: session_start randomly hangs
Description: ------------ On a production site using PHP5 5.0.3 with Apache 1.3.33 we see random session_start hangs. It does NOT happen always on the same page, with the same client, the same frequency or unter the same load. If it happens the process eats up all CPU time util it reaches the 'max_execution_time'. It then leaves a trace in the error log saying: PHP Fatal error: Maximum execution time of 15 seconds exceeded in XXX on line XXX. There are always other pages and lines. I already tried a lot of stuff to see if there is any influence like using 'session_destroy'. I do not use any special session parameters. The actual parameters are: [Session] session.save_handler = files session.save_path = /home/teviaqui/session session.use_cookies = 1 session.name = PHPSESSID session.auto_start = 0 session.cookie_lifetime = 0 session.cookie_path = / session.cookie_domain = session.serialize_handler = php session.gc_probability = 1 session.gc_divisor = 1000 session.gc_maxlifetime = 1440 session.bug_compat_42 = 0 session.bug_compat_warn = 1 session.referer_check = session.entropy_length = 0 session.entropy_file = ;session.entropy_length = 16 ;session.entropy_file = /dev/urandom session.cache_limiter = nocache session.cache_expire = 180 session.use_trans_sid = 0 I am also a developer and might help to debug the code but I need some advice where to lock at! Reproduce code: --------------- session_start (); Expected result: ---------------- I would like to see no processes eating up all the CPU time of our sever. Actual result: -------------- The the moment I have several httpd processes hanging at the same time eating up all CPU time. There are about 120 users browsing the site. At the moment it happens like 30 times every hour! -- Edit bug report at http://bugs.php.net/?id=31915&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=31915&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=31915&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=31915&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=31915&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=31915&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=31915&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=31915&r=needscript Try newer version: http://bugs.php.net/fix.php?id=31915&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=31915&r=support Expected behavior: http://bugs.php.net/fix.php?id=31915&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=31915&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=31915&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=31915&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=31915&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=31915&r=dst IIS Stability: http://bugs.php.net/fix.php?id=31915&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=31915&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=31915&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=31915&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=31915&r=mysqlcfg
