I am running a VbAdvanced/Vbulletin portal site, lately I have been seeing a lot of:
| Code: |

The site works, all php/html pages are returned, however when a child process seg faults a 0 byte page is returned. I have done quite a bit of searching, some references to mod_perl and mod_php, but AFAIK I am not even running mod perl.
I have rebuilt apache, php and am working on glibc now. I am wondering if anyone else has experienced this on apache 1.3, and if a solution was found. |

| Have you checked the urls which were accessed when the child processes have crashed? Could be helpful. |

It is a dynamic php site, there is also a lot of javascript involved. So it is difficult to get any real information regarding which page was served up to see what caused the seg fault
http://www.darkportals.com
I have seen some references to fopen in searches, so I disabled the module that was using it. There is also a module using a popen call, i'm going to have a look at that. |

Yeah and more then likely generated a segmentation fault in the error_log, by the end of tonight I will have rebuilt glibc, apache and php, so with any luck the problem will be over. Otherwise maybe ill explore moving to apache 2 |
