Seems a lot of Mem to me. We're running a Tomcat with several small to

What's your hibernate cache-settings. Do you use lazy collections? Sorry for
asking - but when we started to use hibernate some guys were upset when
discovering that hibernate slurped in their whole DB for each request ;),
because they didn't use lazy collections...

Subject: Recommended Memory Req's
I'm just curious what the recommended amount of memory should be
allocated to a medium sized appilcation running Tapestry 4 / Hibernate
in JBOSS 4.X? Currently on my Dev box I have JBoss heap size set at
512. When testing my application I notice that I am pretty much
maxing that out and am worried about performance on a production
system with mulitple users.
Thanks.

It's more than likely the singletons created at application deploy etc...
Are you re-deploying the application with the server running each time,
or do you do a complete server shutdown?
The singletons are not destroyed during application undeploy.
I have the same issue with the PermGen Out of mempory heap exceptions.
The only solution found is to restart the server (Jboss 4.x) after about
8 application re-deploys.
