Camel with Tomcat (with or without Spring) doesn't release memory
after Stop Restart or Redeployment
Dear Camel Experts,
I'm having a problem using camel with tomcat as the container. For some
reason after several stop/restarts or redeployments the application generate
a java.lang.OutOfMemoryError And I need to restart tomcat
I tried to simplify the problem and discover the same behavior using the
examples in the official release package. Mainly I downloaded:
http://www.apache.org/dyn/closer.cgi/camel/apache-camel/2.15.2/apache-camel-2.15.2.tar.gz
And generated the WARs using mvn install for the following examples:
- camel-example-servlet-tomcat-no-spring
- camel-example-servlet-tomcat
Then deployed any of the WARs generated to tomcat: 7.0.55.
So when I open the tomcat manager and click the button stop, the application
stop gracefully but when I click the button "Find Leaks", tomcat manager
displays the following:
The following web applications were stopped (reloaded, undeployed), but
their
classes from previous runs are still loaded in memory, thus causing a memory
leak (use a profiler to confirm):
/camel-example-servlet-tomcat-no-spring-2.15.2
I also verified the same behaviour using a profiler, when start and then
stop is clicked several times the application generates and the OutOfMemory
error and tomcat needs to be restarted
Thanks in advance for any help or guidance!
Best Regards
Juan Pablo

Dear Christian,
Thanks for the response!
I tried to upload the file from here but it was too large. I created a tgz
file here ->
https://drive.google.com/file/d/0B_7I8JR0jolUWk5GdlpveTZqbm8/view?usp=sharing
The uncompressed file is about 30Mbytes
Mainly the war that I deployed to tomcat was created from the example:
apache-camel-2.15.2/examples/camel-example-servlet-tomcat-no-spring
(provided by the official download package) using mvn install command)
Also If you need it here is the war created:
camel-example-servlet-tomcat-no-spring-2.war
<http://camel.465427.n5.nabble.com/file/n5767613/camel-example-servlet-tomcat-no-spring-2.war>
Best Regards
Juan Pablo

Can you provide a heap dump so that we can have a look which classes are
not unloaded!?
Best,
Christian
