zend_mm_heap corrupted

[demiankatz]

After deploying a beta of my ZF2-based application into production using PHP 5.4.11, I’ve run into problems with the application breaking and filling the Apache error logs with “zend_mm_heap corrupted” messages.  I’ve never seen this before, though perhaps it is somehow related to PHP version; I’ve done most of my development work with 5.3.10.  Based on this StackOverflow thread:

 

http://stackoverflow.com/questions/2247977/what-does-zend-mm-heap-corrupted-mean

 

…it seems that the causes and solutions for this problem are not well understood.

 

It does seem that sometimes the problem can be (but isn’t necessarily) related to use of traits – obviously my own code does not do this since I developed on 5.3.x, but could the issue be related to some of the 5.4-detection logic in the framework itself?

 

I’ll have to try some of the StackOverflow php.ini suggestions to see if I can get rid of the problem, but in the meantime, I thought I would check and see if anyone else had encountered this with ZF2, and if so, whether you had any recommendations.

 

thanks,

Demian

Try disabling some/all extensions. If that helps, try narrowing down the offending ones and update them (or reconfigure, or recompile, or replace).

This helped me the other day.

Demian,

Are you running APC?  If so which version?

Mike

I didn’t actually realize that I was running APC, but I was – apparently it got pulled in by default as part of the Yum package!  It’s version 3.1.14, for what that’s worth.

If you're running APC under PHP 5.4, that could be your culprit; I've
heard many reports of it being unstable with that PHP version.

If you're running APC under PHP 5.4, that could be your culprit; I've

APC does run with PHP 5.4 but it sometimes takes a bit of care.  There is a huge bug with APC 3.1.14 and it was actually removed from PECL: http://pecl.php.net/package/APC

You will want to download and install APC 3.1.13 and force install it over the previous APC installation.

Mike
