Subject: php5-cli: Segmentation fault and zend_mm_heap corrupted while executing piwik update script

Date: Wed, 11 May 2011 12:26:20 +0200

Package: php5-cli
Version: 5.3.3-7+squeeze1
Severity: important

I have a fairly large piwik setup and when the cron job executes the script to update stats, most of the times I get errors of this kind:
/www/misc/cron/archive.sh: line 73: 23673 Segmentation fault      $CMD zend_mm_heap corrupted

thank you

Hi,

please install php5-dbg and provide backtrace:

http://bugs.php.net/bugs-generating-backtrace.php

and possible a isolated (small) test case.

I'm sorry I thing it would be very difficult to provide a test case because I've a large DB and the problem only arise with large data.

Hi Dusty,

   Thank your for the backtrace. Unfortunately I don't see any calls
to execute();  See https://bugs.php.net/bugs-generating-backtrace.php
"Locating which function call caused a segfault"

   I am not intimately familiar with your specific issue so I looked
into it a bit more.
http://stackoverflow.com/questions/2247977/what-does-zend-mm-heap-corrupted-mean

   If the cron job you are running is something that you wrote
yourself you may want to look into profiling/benchmarking your script
to find out if maybe you are having a memory issue (See Stackoverflow
post 4)
   I am really suspicious that your blowing a stack somewhere. Since
you are working with a very large data set this could be a hint.

   I would suggest reusing any objects in your code, also looking at
freeing objects after you are done with them instead of letting the
garbage collector take care of them. If you can come up with a test
case I would
   be more than happy to help you so more. Right now I don't have much
to go off of.

   Thanks]

Hello,

Do you still have the same issue with 5.4 version on wheezy?

Thanks,

No reply from OP, so closing the bug as it happened only in oldstable.
