On a heavy loaded webserver apache 1.3.27 performs well even better with apache
2.0.46 but the httpd-processes suddenly get killed by a segfault as seen below
in the error_log:

Below the strace output from a proces died by a sigfault, the "sigreturn()" till
the "<... rt_sigsuspend resumed>" line are repeated very often but i neglected
to paste the whole log in here:
