Package: Apache2 related
Bug Type: Bug
Bug description:apache2 / php5ts crashes, sometimes reporting zend_mm_heap corrupted
Description:
------------
Windows 2008 R2; apache 2.4.12 (32-bit) from apachelounge.
was running 5.5.24/32-bit just fine.
upgraded to 5.5.26/32-bit, and immediately started getting errors like
this:
Faulting application name: httpd.exe, version: 2.4.12.0, time stamp:
0x54c90386
Faulting module name: php5ts.dll, version: 5.5.26.0, time stamp:
0x5578acb1
Exception code: 0xc0000005
Fault offset: 0x003ce564
Faulting process id: 0x16f0
Faulting application start time: 0x01d0b773c098bfd0
Faulting application path: C:\Program Files
(x86)\Apache2.4\bin\httpd.exe
Faulting module path: C:\Program Files (x86)\PHP5.5\php5ts.dll
The crash occurred about 40 times in one hour.
Sometimes, but not always, the apache error log contained:
zend_mm_heap corrupted
Reverting to 5.5.24 completely removed the problem.
Unfortunately, I cannot recreate the program in a development or test
environment; and I cannot afford to cause the problem in production
again. Therefor I cannot provide a backtrace.
The problem seemed mainly to occur when generating large PDF files,
which in our app involves merging PDFs.
We are using:
* SQL Server 2008 R2
* ImageMagick 6.7.9-Q8
* WkHtmlToPDF 0.12.2.1
* ghostscript 9.14 (64-bit)
* PDFtk 2.02
PHP modules:
* PHP/PDO driver for SQL Server (v3.0.2, 32-bit)
* igbinary
* xcache (v3.2.0)
If there is any way I can provide more information, short of causing the
problem to occur in production, I would be very happy to do so.
