Jan 16 17:35:42.229 [notice] cull_wedged_cpuworkers(): Bug: closing wedged cpuworker. Can somebody find the bug?

Using libevent-1.1a on a Linux i586 system, the above message appears in my log. Tor server does not seem to crash; service remains viable.

Hm. Is this repeatable?

That message only occurs when the cpuworker has been working on the same
public key encryption operation for 60 minutes. Each operation should
take far less than a second.

Perhaps this occurs when your system becomes so slow that Tor doesn't get
any CPU time at all, e.g. because it spends all its time swapping?

Or perhaps it occurs if your clock is bouncing all over the place and it
suddenly skips forward by a few hours?

Let us know if you learn more.

I have increased the timeout to 12 hours, from 1 hour. We haven't heard
from many people who experience this, and perhaps this will help to
narrow down the set even more.

I am guessing that most people who experience this are running on an
extremely underpowered computer and it really is swapping for the whole
hour, thus starving Tor.
