100% CPU load
After a few days of operations (roughly a few hundred connections in total, rarely more than 5 concurrent ones) the ratchet task locks up one CPU thread permanently until restarted. It keeps working though.

I installed the libevent PHP extension, but it didn't solve the problem. It doesn't even seem to be related to real workload.

I wasn't able to diagnose this problem in any way. Is there some sort of debug output one can enable?

This is the startup script:

This is the application class:

Both are really rather simple, I don't see anything that could end up in a loop ...

Any ideas/suggestions how to debug this?

P.S.: This is a Ubuntu 12.04 distro PHP installation.
