High CPU usage from PullRequestDetectionBackgroundThread in Bamboo 6.0

[pscheit]

Hi there,

maybe someone can help me:

When I start bamboo it fires up three javathreads with 100% cpu usage. I'm using an applink to a bitbucket server. When I enable debug logging for the class: com.atlassian.bamboo.plugins.stash.BitbucketServerPullRequestDetector with loglevel ALL I get a lot of:

DEBUG [6-PullRequestDetectionBackgroundThread:pool-12-thread-3] [BitbucketServerPullRequestDetector] Fetched 0 open PRs from <repository>

A LOT (like every 100 ms).

Can anyone help me?
Best regards Philipp

Looks like a bug - how many Bitbucket Server repositories do you have defined?

[pscheit]

14 linked repositories
restarting bamboo removes the thread instances randomly

It's a bug
