[jira] [Created] (CONTINUUM-2758) High CPU and memory load when
preparing builds with many build results
Brent N Atkinson created CONTINUUM-2758:
-------------------------------------------
Summary: High CPU and memory load when preparing builds with many build results
Key: CONTINUUM-2758
URL: https://issues.apache.org/jira/browse/CONTINUUM-2758
Project: Continuum
Issue Type: Bug
Affects Versions: 1.4.2
Reporter: Brent N Atkinson
Assignee: Brent N Atkinson
Fix For: 1.5.0
Found while addressing CONTINUUM-1621, due to the way that Continuum find the previous build results during build preparation, memory and CPU load increases proportionally to the number of build results for a project. This will eventually result in 100% cpu utilization and {{OutOfMemoryErrors}}.
To produce this, I imported a project and replicated a set of build results until there were over 1,000,000. When I restarted Continuum, the CPU and memory utilization (viewable using jconsole) would spike until it threw and OOME.
By producing a heap dump and analyzing it, I was able to pinpoint the problem area, a bad query in the DAO.
