-----------------------------------------

             Summary: Huge changelogs eat all the Java memory
                 Key: JENKINS-13109
                 URL: https://issues.jenkins-ci.org/browse/JENKINS-13109
             Project: Jenkins
          Issue Type: Bug
          Components: perforce
         Environment: Windows Server 2008 HPC Edition
64-bit JVM 1.6.0_29
Running Jenkins service with "<arguments>-Xrs -Xmx2048m 
-Dhudson.lifecycle=hudson.lifecycle.WindowsServiceLifecycle -jar 
"%BASE%\jenkins.war" --httpPort=8080</arguments>"
            Reporter: Mikko Tapaninen


With really huge changelists the p4 plugin can run out of java heap space. At 
least it looks like the reason for memory problems would be huge changelog.xml 
files. An example case:

- a changelist with > 400000 files
- results in a changelog.xml size > 110MB
- Jenkins runs out of memory: {{java.lang.OutOfMemoryError: Java heap space}}

Maybe there should be an option to limit the amount of files that p4 plugin 
reads to from changelists?
