JENKINS-46579 maven event spy: Fix concurrency issue in the handling of the output file

FYI I have created JENKINS-46609 . pino could the Maven process could have been killed by the operating system? I saw this problem in docker/cgroup environments.

Well well, that was it. The maven process was getting killed for no apparent reason. I played with the java Xmx and it looks much better now. I don't understand why it would fail with Xmx3G when in dev we use Xmx2G but I have increased this to 4G and it seems to work.

Can you clarify which Xmx you are referring to?
Do you run this process in a Docker container or in cgroups?
Do the memory of this agents fits with the sumof the memory of all the known processes ? Slave.jar + mvn process + maybe mvn sub processes
Can you monitor the memory, CPU and load of this agent to detect problems?

Fixed by https://repo.jenkins-ci.org/releases/org/jenkins-ci/plugins/pipeline-maven/3.0.1-beta-1/pipeline-maven-3.0.1-beta-1.hpi
We detect when the Maven build has been killed and don't display this confusing XML parsing exception. See Pipeline Maven Plugin> Why do I see messages...

pino could you test the 3.0.1-beta?
https://github.com/jenkinsci/pipeline-maven-plugin/releases/tag/pipeline-maven-3.0.1-beta-2

I will, I am however on vacation at this time.

Thanks pino, as I have already tested, we may release before you are back from holidays

v3.0.1

we run version 3.6.11 and still see this from time to time:
