[Zope] zserver restart

[Peter Sabaini]

zopistas,

during load testing i often see zope / zserver restart or exiting
silently even if the loads are rather moderate.

i'm doing my load testing with apache benchmark, concurrency level
around 10.

doing:

 =======================
> ab -n 500 -c 10 -v 2 -k
http://mysite:8080/tstfolder/test

GET /tstfolder/test HTTP/1.0
User-Agent: ApacheBench/1.3
Connection: Keep-Alive

Accept: */*

---
Broken pipe  
 =======================

gets me a broken pipe on the one end, and on the other i can see
zserver restarting, or just dying.

/tstfolder/test is modeled after my real application, fairly expensive
db stuff.

/tstfolder/test is

<dtml-in "_.range(1,50)">
<dtml-in some_simple_oracle_select>
<dtml-var titel>
</dtml-in>
</dtml-in>


"some_simple_oracle_select" being a simple zsql method.

the system is zope 2.1.4 on a suse linux 6.1 

we're going into production soon and we will have to support medium
loads -- can anybody help?

peter.
