[Zope] MemoryError that brings my zope to its knees

[Pascal Peregrina]

That looks wierd... Has the instance been running for a while when you
copied the content of the Cache Parameters tab ? I would have expected many
more connections (instead of just 2).

Can you give us your zserver-threads value (zope.conf) ?

Thanks.

Pascal

When we started having this problem the box only had 1GB of RAM so we  
replaced that RAM completely and put in a fresh 4GB of RAM to  
hopefully get rid of the problem.   This box is also running 3 other  
Zope instances, but the other don't exhibit this problem.  This  
instance has 15 plone site instances in it.  The others only have a  
couple plone sites each.

This problem will happen and there will still be 1GB of free RAM and  
it hasn't touched the swap at all.  We are running FreeBSD 4.10 on  
this box.

I'm assuming it isn't changed since it isn't in our zope.conf.  Must  
be a newer config that we didn't have from an old zope that this one  
was upgraded from.

Here are the details from the Cache Parameters tab in the ZMI on this  
ZEO instance:

Total number of objects in the database   282934
Total number of objects in memory from all caches    6512
Target number of objects in memory per cache    10000

Total number of objects in each cache:

Cache Name                  Number of active objects    Total active  
and non-active objects
<Connection at 09e5684c>    6048                        18746
<Connection at 0e92902c>    464                         1249

Total                       6512

Thanks,
Calvin
