Hi,
We are using Apache 2.2.23 built using source with default settings. By
default it uses prefork and we use mod proxy and mod rewrite.
Currently apache is crashing with Seg fault errors but the stack track
captured using debugging tool shows exit without core file. Please find
below the beginning and end of the trace.
Program received signal SIGSEGV, Segmentation fault.
