error_log Segmentation fault (11)

[ldejager]

Hi,

I've been experiencing a lot of errors on a FC3 machine... my httpd error_log get's filled with Segmentation fault (11) when people try to access horde/imp.

The server has been recompiled with a higher FD_SETSIZE than normal, and I have rebuild apache and php with the new FD size..

Below is the output of gdb on a core dump, can anyone please point me in a direction as what could be wrong?

second core... I stopped it from dumping core right after this as it's filling /tmp up at a very fast rate
