[Zope-dev] Problems with session on ZEO

[Gerhard Schmidt]

Hi, 

we have some problems with our tempstorage on out ZEO client. 

We are running 6 zope Frontend server and one ZEO server. Serving
Both main and temp storage. 

I runs well for some days. But than it stops working an reports the 
following error

Traceback (innermost last):
  Module ZPublisher.Publish, line 101, in publish

SystemError: error return without exception set

Restarting the zeo server and one frontend fixes the problem for some 
time. 

i am running Zope 2.7.2 and Python 2.3.4 

Here is the zeo config 

%define INSTANCE_HOME /data/zope/zeo

<zeo>
  address 7700
  read-only false
  invalidation-queue-size 500
  # monitor-address PORT
  transaction-timeout 10
</zeo>

<filestorage main>
  path $INSTANCE_HOME/var/Data.fs
</filestorage>

%import tempstorage
<temporarystorage temp>
   name temporary storage for sessioning
</temporarystorage>


<eventlog>
  level info
  <logfile>
    path $INSTANCE_HOME/log/zeo.log
  </logfile>
</eventlog>

Bye
