[Zope] zope unresponsive

I have posted this several times, but have not until now been able to
get DeadlockDebugger installed.  I see several people have had this
problem, but no-one has posted a solution.

 

zope 2.9.5 + zeo
pythonm2.4.3
Red Hat RHEL 4
Plone 2.5.1
 
Our zeo clients hang intermittently.  We have no way of reproducing the 
problem, but it occurs daily.  The client hangs and a restart seems to
fix the 
problem.
 
In the event log with tracing on we get
 
Trace zeo.zrpc.Connection(C) wait(16697) {server:8100} pending, async=0
 
There are hundreds to thousands of these until the server is restarted.
 
In the zeo log we get
 
Error caught in asyncor asyncore.py
 
error:(110,'Connection timed out')
 
We have been trying to track this down and have had no luck.  Does
anyone have 
any suggestions?  Below is our deadlock debugger output
