Memory leak during load testing
-------------------------------
Key: JUDDI-267
URL: https://issues.apache.org/jira/browse/JUDDI-267
Project: jUDDI
Issue Type: Bug
Affects Versions: 3.0beta
Reporter: Kurt T Stam
Assignee: Kurt T Stam
Fix For: 3.0

I ran a load test comprising of 30 virtual user continuously executing a the
following senario on a jUDDI node:
- publish a business to the node with a unique name;
- publish a random number of services (>0 but <8) under that business;
- and search for the newly published business name.
This was supposed to run for two hours but the application crashed after 1h
46m. As can be seen in the attached jconsole screenshot, the heap memory usage
goes up almost linearly during the load test until it hit the maximum alloted
memory, 1G (inserted 'export JAVA_OPTS=-Xmx1024m' in startup.sh). Then, it hung
around one gig as the request's response times got longer and longer as can be
seen in the attached XLT report at about 11:25 (go to 'Requests' via the
navigation drop down in the top right corner, most easily seen on the
'Averages' graphs). Eventually, I started getting 'java.lang.Exception: GC
overhead limit exceeded' and 'java.lang.Exception: Java heap space' exceptions
(stacktraces can be seen under 'Errors' in the XLT report) and the application
crashed.
