--- Comment #6 from Seann Herdejurgen <se...@herdejurgen.com> --- I am still able to cause deadlock now even using RAM disk. I wrote the following script to analyze running httpd processes when I encounter deadlock. #!/bin/sh for pid in $(pgrep -u apache httpd); do pstack $pid | egrep 'lock|modperl_tipool' done Here is sample output when a deadlock occurs: #2 0x00007f1bf03dcb73 in modperl_tipool_pop () from target:/etc/httpd/modules/mod_perl.so #2 0x00007f1bf03dcb73 in modperl_tipool_pop () from
