Confluence stops communicating, any ideas?

One of our installations of Confluence 5.5.7 on RHEL 6 stopped suddenly responding. Confluence is behind an Apache ajp proxy The Apache error logs give messages like

[Thu Apr 09 12:04:43 2015] [error] (70007)The timeout specified has expired: ajp_ilink_receive() can't receive header (error log)

[Wed Apr 08 14:56:49 2015] [error] ajp_read_header: ajp_ilink_receive failed[Wed Apr 08 14:56:49 2015] [error] (70007)The timeout specified has expired: proxy: read response failed from (null) (localhost) (ssl error log)

 

Confluence and Tomcat think everything is fine: the logs contain no error messages.

This started  suddenly without any changes made to the configuration. Restart and boot won't help. Any ideas what this could be?

Yes, there was some kind of deadlock in the Crowd server and it made Confluence noncommunicative. Restarting the Crowd server helped!

We are using Crowd 2.8.0 for authentication. Did not mention it as this did not look like an authentication problem.

Indeed, the Crowd server (RHEL7) was patched and booted at the time the problem appeared. Unbelievable, but cannot be a coincidence.
