[ZDP] zope hangs with open connections

[Veiko Schnabel]

i use zope with an Apache and the pcgi-wrapper and it works actually fine but 
sometimes the server takes no more connections
one z2.py process is running with over 90 % of cpy power
and netstat -an looks like

and around 1000 of the following
unix0[ ] STREAM CONNECTED 111262442 /zope/htdocs/var/pcgi.soc
unix0[ ] STREAM CONNECTED 111262436 /zope/htdocs/var/pcgi.soc

after restarting zope everything is working fine again
may there is a way to get more informations in the log-files, something like 
log-levels

if someone could send me help for this , would be great

thanx
