I would consider the segmentation faults to be bugs. The question is whether they are bugs in httpd or in mod_security... Looking at the backtraces I noticed that most threads are busy in a syscall (i.e. poll(), read() and the like) or waiting on a thread mutex (i.e. pthread_cond_wait() etc.). Those threads are blocked and most likely do not actively contribute to a segfault. In both segfaults you can find a thread that is currently running a signal handler (i.e. kill()). If I remember correctly, it is quite error prone to handle signals in multi-threaded applications. I would assume your segfaults are related to these typical signal handling issues with multithreading. Hope that helps... Regards, Micha
