If you want to save memory, store the logs as files that you archive as build artifacts. Storing large logs inline in the junit xml files will cost you a lot in memory. But if you have the memory, go for it.
Sun JVM option -XmxNNG sets the heap to NN gigabytes. Run "java -X" to see what you can tune. How exactly you change it, depends on your platform and the way you start Jenkins. -- Sami 2012/3/2 Gaetan <gae...@xeberon.net>: > Hello > > I'm starting to have a java heap error when parsing the junit tests. > I have a bunch of 3000 tests that might have some long logs (the total size > of junit files is around 200 Mb), but I hope jenkins is able to handle > this). > > How can I increase the HEAP size of jenkins ?
