[Zope] zope process goes to sleep

We have Zope 2.6.1 (upgraded) running behind Apache 2.0 on a Redhat 8 
dual processor machine with Py 2.1.3. Its been live for quite a few days.

Now every night at around 3-5 AM the server sort of stops responding. A 
ps -ax still shows the process running, and a ping to port 8080 on the 
machine returns a valid response, just that the server doesnt respond 
and Apache returns a proxy error.

Also before that happens the apache logs show that there are not hits 
for quite some time.  
Once I restart the zope process everything sworks fine then.

Any ideas as to what might be causing that? Has anybody seen that before?/

My start script:

#! /bin/sh

umask 077

export INSTANCE_HOME="/var/local/zope"
export ZSYSLOG="/dev/log"
export EVENT_LOG_FILE="/var/log/zope/Zope.log"

/usr/bin/env bin/python $INSTANCE_HOME/z2.py \
        -D \
        -Z1 \
        -C \
        -t 20 \
        -z /var/local/zope \
        -u zope \
        -X \
        -a \
        -P 8000 \
        -m - \
        -p - \
        -f - \
        -M /var/log/zope/detailed.txt \
        -l /var/log/zope/zserver.txt
