ID: 39448 Comment by: jwagner at computing dot dcu dot ie Reported by: jschwabik at koop dot cz Summary: Maximum execution time exceeded even if is unlimited Status: No Feedback Type: Bug Package: Performance problem Operating System: CentOS release 4.3 PHP Version: 5.2.0 Block user comment: N New Comment: Regarding the unpredictable moment when execution stops, please note that max_execution_time only applies to time spent by crunching php code, i.e. the 30 seconds stop counting down when you run a shell command, query your mysql database etc. Therefore, the 30 seconds may be over after 10 minutes or 5 hours. It all depends on what your php code is doing. Theoretically, if php automatically parallelised code on multiple cores, the 30 seconds could also be over even quicker than 30 seconds real time. Regarding the set_time_limit(0), you need to be in soft mode in order to be able to raise your limits.

This problem starting happening randomly within the code, and there doesn't seem to be a reason for it other then it seems to be related to MySQL calls... but I haven't taken the time yet to test that theory. Its also is random which makes it VERY hard to create a reproducable version. I'll be upgrading PHP and MySQL tonight and will then spend some time building a test case to reproduce this problem as its becoming more frequent as of late. ------------------------------------------------------------------------ [2006-11-17 01:00:01] php-bugs at lists dot php dot net No feedback was provided for this bug for over a week, so it is being suspended automatically.

I tested some settings and they worked, so I though this problem is a mbstring problem - but it possibly occurs also with other ini settings... ------------------------------------------------------------------------ [2006-11-09 17:10:02] tony2...@php.net Not reproducible. ------------------------------------------------------------------------ [2006-11-09 12:39:24] jschwabik at koop dot cz Description: ------------ I've got script running from linux shell and sometimes it crashes with "Maximum execution time of 30 seconds exceeded in some line" error in the script. The command on which it crashes is unpredictable. The script is runnig sometimes 10 minutes, sometimes 30 minutes and crashes on different lines. (It never runs 30 seconds). I am running it from command line (CLI) (max_execution_time should be 0) an I set it with set_time_limit(0) to 0. I've tried two servers 4 php versions (4.4.2, 4.4.4,5.1.6,5.2.0) In my php.ini is max_execution_time set to 0. Sometimes it ends on ifx_fetch_row(). Sometimes it ends on mktime().
