I am running zope 2.5.0 on Solaris (I had installed the binary version) using
ZServer. I am able to access the web management interface with
the initial user admin  created at installation time.

Later I had added a user "portal_manager", which could login without any problems.
About one week later I couldn't login with this user but could still login with user
admin.

Restarting ZServer solved the problem. This is not a problem for a test site,
but in a production environment we don't want to restart  ZServer each time a user
can't login.


Dieter Maurer  indicated this is due to some memory problems in older versions of
zope.

But I am using zope 2.5.0 and this problem might still exist.

Is there a solution for this problem (without restarting Zserver) ?
