Summary 0004529: mod_caucho threading issue
Description (rep by remkodev)

See [^]

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.
