From which version is this implemented?

We are using LTS 1.480.3
-Djava.awt.headless=true -Xms1g -Xmx6g -XX:MaxPermSize=512M -XX:+UseParallelGC -XX:ParallelGCThreads=16 -XX:+PrintGCDetails -XX:+PrintGCTimeStamps -verbose:gc -Djava.net.preferIPv4Stack=true -XX:+HeapDumpOnOutOfMemoryError

Java version is
Java(TM) SE Runtime Environment (build 1.7.0_17-b02)
Java HotSpot(TM) 64-Bit Server VM (build 23.7-b01, mixed mode)

Thanks,
Viktor

The newer version's read the build history on demand.

And you can control the memory usage as well via parameters like:

JAVA_ARGS="-Djava.awt.headless=true -Xms1g -Xmx10g -XX:MaxPermSize=1G -XX:+UseParNewGC"

This is a very optimal setup for us. ~100 nodes, ~200 jobs with thousands of tests (heavy loaded jenkins cluster running 0-24 and building continuously)

Hi,

Jenkins seems to consume an awful lot of memory. As I understand it is due to keeping build logs in memory for one. My question is what other factors influence jenkins' memory consumption and what can I do about it? Also, is there a way to flush the memory on demand or force a GC without restarting the server?
Thanks for your answers!

Viktor
