The kernel is 2.4.7-10. Zope 2.5 on Red Hat 7.2 python 2.1.3 Here is what I think the problem is: Some object or code was introduced on Tuesday morning. The users are beginners so they could have introduced a never ending loop or something of that sort. I turned on profiling to see if thre was anything in particular consuming a lot of time. A the top of the list was Connection.py.
Is there a way catch that non terminating loop? This non-terminating loop is just a theory I have. I could be completely wrong. Are there other things I could look at for clues. >>> Toby Dickenson <[EMAIL PROTECTED]> 09/05/02 06:46 AM >>> On Thursday 05 Sep 2002 2:58 am, Ahsan Imam wrote: > Hello All, > > I am currently running zope 2.5 and python 2.1.3. Are you actually seeing the zope processes use too much memory? 2.5.x have a ZODB cache mechanism that does not respond well to memory pressure. If your application touches many objects per transaction then memory usage may grow out of control. 2.6 improves this significantly. > The machine has 2 gigs of > rams and is running on Red Hat 7.2.

Are you sure you are interpreting the output from 'free' correctly? It is often misinterpreted.
