Hello Everybody!
I just got OutOfMemoryError in our production application (wicket 1.3rc2).
Any ideas what was the reason?

java.lang.OutOfMemoryError: Java heap space at
org.apache.wicket.util.string.AppendingStringBuffer.expandCapacity(AppendingStringBuffer.java:158)

org.apache.
Hi Artur,
I suppose it isn´t the AppendingStringBuffer that is causing your problem.
Did you attach a profiler? http://YourKit.com is just one example of a
good, easy to setup&run profiler.
java.lang.OutOfMemoryError: Java heap space at
org.apache.wicket.util.string.AppendingStringBuffer.
Did you try starting your app container with extra memory, by default
java does not allocate that much, a common webapp is likely to run out
of memory with the default settings.

I didn't. It happened in our production server and only once. But this kind
of error

I wanted to ask about it.
i´d suggest you duplicate your productionserver and attach a profiler
while load-testing with some usual tool like jmeter etc in order to see
if

I start tomcat with:
-Xms512M -Xmx768M
Should I consider something else?
Runtime.getRunt
Nowadays its also many times the perm heap thats to small. Dont know
if that is the cause for you because i think it will say that in the
exception (the propery for that is a special XX system property dont
have that at hand)

Yes, use a profiler. Everyone who is working on a production system
should regularly use a profiler and load testing tool to ensure there
are no memory leaks etc. In my experience and if you search threads in
this lis
yeah but South Africa has 3G no idea what thats gonna cost me.
But also internet cafes so i should use those more often..

the permgen space param = -XX:MaxPermSize=256m
Just in case.
