I can't reproduce it so far and the backtrace shows nothing related to PHP itself. Previous Comments: ------------------------------------------------------------------------ [2006-08-06 08:39:36] mail at dasprids dot de Well, I still can crash the Apache2 with a graceful restart. Here I provide the gdb backtrace until the graceful restart: Program received signal SIGUSR1, User defined signal 1. [Switching to Thread 1077000416 (LWP 17060)] 0xffffe410 in ??

As far as I know at the moment, they tracked it down to mysql and mysqli, but at my point it did not help. I'm using no accelerators or other 3rd party software on my server.
