I've recompiled apache and mod_jk with apr 1.4.4, also removed php and
switched to prefork to make debugging easier, below is the GDB output of
the process that is hanging at 100% cpu.

Apache starts ok and does not start eating at the cpu untill an http
request is made to it.

Thread 1 (Thread 8014041c0 (LWP 100847/httpd)):

) at strings/apr_fnmatch.c:230

Please let me know if i should run any other commands in GDB.
