-------------------------------------
That's better, yes. Can you also provide the rest. Otherwise this is needle in
the haystack.
> Maven intermittently hanging at end of multithreaded build
> ----------------------------------------------------------
>
> Key: MNG-6474
> URL: https://issues.apache.org/jira/browse/MNG-6474
> Project: Maven
> Issue Type: Bug
> Affects Versions: 3.5.2
> Reporter: Beirtí Ó'Nunáin
> Priority: Major
> Attachments: thread dump.txt
>
>
> I can't reproduce this with a small skeleton project. It has only started
> happening since we upgraded from 3.3 to 3.5.
>
> I have a multithreaded multi-module build which builds a number of large
> (300mb+) artifacts upon SVN commits. I'm running the following goals:
>
> mvn clean deploy -T 1C
>
> Reasonably often, perhaps 1 in 10 builds, the build hangs just before where
> I'd expect the build to have finished. I'm guessing that maven is attempting
> to install an artifact to the local repository (looking at the stack trace)
> while the build is about to complete as when I compare the build log from the
> hung build to a successful build, the following line is the "Reactor Summary"
> This issue happens both on my local machine and on our TeamCity server (Both
> multi-processor, multi-core 14 vs 32 cores)
> The Thread dump isn't indicating any kind of DeadLock. Our sysadmins have
> checked the box for any antivirus scanning which may be impacting the file
> copy indicated in the log but can't see anything going on at that time.
> Full thread dump from TeamCity attached
