|Summary||0004529: mod_caucho threading issue|
(rep by remkodev)
See http://forum.caucho.com/showthread.php?t=27741 [^]
The thread's last resin function is cse_free_lock
cse_free_lock(config_t *config, void *vlock)
After some research, it appears that apr_thread_mutex_destroy(vlock); is not thread safe.
We figured that because our webservers uses multiple resin servers (around 6) in each vhost/apache instance these will cause the race condition over the thread_mutex_destroy method.
Today I altered the configuration of the most busy app ( Note: 0000090% off the hits) to be proxied to a seprate webserver with only 1 resin host configured. This setup did not cause a single hanging process for over 4 hours.
