Hi, We have setup a hudson with various projects (about 20) they are all
scheduled to build sometime at night. We experience regularly outofmemeory
problems with the builds. Most of the time this happens when the reports of
findbugs or jdepend are parsed. We use tomcat6 on ubuntu 9.0.4/jdk1.6. Adding
more and more memory to tomcat did not solve the problem. We ended up to
Xmx1600m but it still occurs.It only take more days. It seems to me that one of
the two plugins have a memory leak but I can not be sure since they need a lot
of memory to parse.
