Segmentation fault (11)


Hello all,

We are using Apache with PHP for one of our web application. Apache and PHP were compiled and built on this system as the depot bundle did not provide few modules that we needed.

Now we are seeing Segmentation fault (11) errors being logged in our Apache logs. The website becomes inaccessible after some time.

I want to know more about the Segmentation fault (11) error. Is it a hardware problem ?, or the OS (we use hp-ux 11.0) ?, if yes then should have to try any OS patches for this ?

Attached is an extract of the apache log.

Thanks,
Vishwa

Hi Vishwa,

You're getting SIGSEGV faults & these are most often related to the kernel parameters maxdsiz, maxssiz or maxtsiz being exhausted.
These values & possibly the shared memory related values need to be tuned to your application needs.

HTH,
Jeff

Vishwa,

Please disregard that patch number, I grabbed the wrong O/S. My apologies.
