Hi Daniel,

Thank you so much for your response. The error does not occur too often for
me either, so I suppose I could schedule Resin restart e.g. every night and
that would keep it away for me.

We have not developed the application (an open source CMS system), but are
just maintaining it, so not that keen to start profiling it if I can get
away without :)

Regards,

Olli

All I can say is that during development, when we reload the web 
applications many times, when the container is about tu run OutOfMemory 
it gives similar error messages to the ones you describe (classes not 
found that have already been used etc).

In our case, it seems to be related to classloaders having some 
references that are not cleaned appropriately, sometimes by foreign code 
like DataSources holding to drivers but as it is usually just a problem 
in development, we have not had time to chase it in detail.

In any case, the symptoms you describe are usually a indication of an 
incoming OutOfMemoryError, the reason itself for the error is another story.

I know that does not help much, but unless you are reloading your 
application multiple times, I would look for a memory leak.

Good luck!
