[ZODB-Dev] ZEO client leaking memory?

[Fritz Mesedilla]

I hope you can enlighten me.
Is this topic somehow related that our load-balanced Zope clients needed to
be restarts once ina while because if not, the webpages become slow?

The thing is, the ZEO server is running on one instance. Then the clients
need to be restarted like every 4 hours or else it will stop serving pages.

Yes, the memory on the clients also take in a lot.
