Ed Palazzo commented on JENKINS-12672:
--------------------------------------
I've had the fix in place for a week now, and the problem has not recurred. A
very good sign! Thanks again for the quick fix. I'll let you know if anything
changes here.
> Jobs take a long time to complete - get stuck sending success/failure email

> Key: JENKINS-12672
> URL: https://issues.jenkins-ci.org/browse/JENKINS-12672
> Project: Jenkins
> Issue Type: Bug
> Components: perforce
> Affects Versions: current
> Environment: Jenkins 1.450
> Perforce plugin 1.3.7
> Red Hat Enterprise Linux 4.5
> Reporter: Ed Palazzo
> Assignee: Rob Petti

> We've noticed that sometimes our jobs get in a state where they're taking a
> long time to complete. Investigation reveals that the maven build has
> completing successfully, and it's "stuck" trying to send a success email.
> Left alone, the build will eventually complete but a 10 minute build may take
> several hours to succeed and blocks other jobs since the executors are busy.
> Manual monitoring and intervention is usually required to free up the jobs.
> Here's an example thread taken from a Jenkins thread dump that shows the
> "stuck" job. It appears to be processing the change list to retrieve the
> checkin user(s) that checked in code. Why is this taking so long?
> The exact stack changes with each thread dump, but it is consistent up to
> PerforceChangeLogSet.parse(PerforceChangeLogSet.java:111).
> "Executor #2 for master : executing markview-7.0.x_document-server #103"
