Lately I see alot of permgen errors
With Hibernate I see javassist bytecode provider causing permgen errors
thankfully a solution is to use the cglib provider by changing
hibernate.properties hibernate.bytecode.provider.javassist to
hibernate.bytecode.provider cglib
http://forum.springframework.org/showthread.php?t=31255
2.1_03 cglib jars available at
http://sourceforge.net/project/showfiles.php?group_id=56933&package_id=98218
The bigger problem is how to deal with permgen errors caused during multiple
Tomcat webapp invocations .. some suggest switching JVM to JRockit?

Thoughts?

Subject: RE: HTTPS service
I see this more often that I'd like on my development system. When I look
in
the stdout log file, I see a "ConcurentModificationException" in the
trace.
I have found that I reduce my chances by waiting a few more seconds before
I
restart.
For memory issues, look at your app and make sure that you don't have any
objects that have circular links or are being held in static space and not
released. Also if your server is over taxed, not very often the case, the
GC
may not run very often. Look at efficiencies in the code. Maybe you can
reuse some objects or cut down on the number or size of some objects. Java
is a wonderful language but I think it allows a little laziness in coding.

Subject: HTTPS service
Hi all ~
When restarting Tomcat Services (due to increasing memory); our HTTPS
site gives a 404 error (Page cannot be displayed). The HTTP site is just
fine. After restarting the service the second time, HTTPS is back up and
running. Has anybody experienced or have heard of this issue before?
Tomcat 5.0.28
Windows 2000 SP4
RAM - 8GB
CPU - Intel 3.20ghz
Thank you
