This should take care of it.

If by "known" you mean I can point you to the code segment causing it, then 
no. However, I have cured several leaky sites in the past by moving away 
from XUF and your excessive DateTime refcounts rang a bell.

Do you have the possibility to test the site without XUF? At least make 
sure you have the latest version. Do you have a large number of users?

You could try to put ZSP_OWNEROUS_SKIP=1 in you start script, and see 
whether it makes a difference. If it did, it would indicate a problem 
related to the user folder and not the catalog per se.

Disclaimer: This is guesswork based on events a long time ago. Current 
versions of XUF may very well work fine.
