Hi all,
I have a java web application running on tomcat and I get java heap
space not enough error temporarily. Each time I am increasing the JMV
heap option by modifying the system variable CATALINA_OPTS. However,
this solves the problem temporarily. I get the same error when I work
for some more weeks on the development of the application.
Can anybody help me solve the problem?
You probably have a memory leak in your application.
The first thing to check thoroughly, and I do mean thoroughly, is that
you are properly closing all database connections and related objects.
Don't assume that you have done so - check every location in the code
carefully.
Depending on which OS & JVM version you have, (you didn't say - so we
have to guess), there are tools you can use to examine the application's
state and memory consumption.
Google "memory leak", "jmap" and "thread dump"

Thanks in advance.
