Empty contentlist in portletselector

ExpressPortal 5.2.1 running on jboss/suse 9.

When the server starts, all is well, after a while, the problem is there.
When a user wants to personalize, he tries to add portlets to a page. But
the categories list only has "all categories", and shows "xx" in the
contentlist. So no portlets to add in his list. After a restart of the
server the portal runs fine again, only it occurs to often. Admin or normal
user makes no difference. All other things run ok during the error. Another
instance runs fine during this error, so database and ldap are fine.

Does it look like something we can solve, or is this going to be a novell
support call?
