This is the problem (not apache2). We (the Caudium Group) has this problem when we tried to make a SAPI for Caudium which threaded. Even with makeing mutexes or whatever the whole server was segfaulting or lock it self because of non thread safe coding. If you use php as mod_php with apache2 I recommand you to use NPM=prefork... /Xavier -- Xavier Beaudouin - Unix System Administrator & Projects Leader.
