memory usage
Hi everyone,
I'm not quite sure where to post this problem - the tomcat, tapestry or
cayenne mailing list - but here goes...
I have an app built on the mentioned technologies. I click arround and
monitor the memory usage (using the Win task manager - good enough for
rough measurements). The memory usage seems to grow up to a 100 MB
(Cayenne accesses a single table of about fifty attributes and a 1000
rows - don't ask) and sometimes - I can't reproduce the problem now -
the app brakes when trying to open a new page. The exception says
something about not having enough memory.
Ring any bells, anyone?
Thanks for your effort,
Tomislav

Yes -- if a Java app is out of memory,
1/ invest in a profiler to see whether there's a resource leak
2/ increase the heap such that the JVM has more space in which to create
objects
btw, please post a *new* message when writing to the list. Replying to
an old (unrelated) message confuses thread-aware mailers, which makes
your question harder to find (and thus answer).
