RE: [Zope] MemoryError that brings my zope to its knees
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.

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. > Have you changed the default pool-size in the section ? 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.
