Description:
------------
See the following bug report: 
https://bugs.launchpad.net/gearmand/+bug/802850

It seems like it happens at random and only under heavier 
load.  When the workers are killed the server returns to 
normal and 
after the restart of the worker it seems to function fine.

What I've noticed is two main things between a working worker 
and a non-working worker (basically when things are fried).  
The 
working ones block and the non-working ones stop blocking but 
simply DDoS the gearmand process.


Expected result:
----------------
I would think that the duration of time should not matter 
that the worker is running.  The fact that it stops blocking 
should never happen while it is sitting in it's while loop.

The fact that it DDoS the gearmand process means that it is 
likely losing some pointer to the connection and unable to 
resolve itself.  It does not give any useful error message 
but continues in the way above until killed.

Actual result:
