Why does it stop running bydy on the crown?

Question

System administration

An old situation ..
I have the "bitbuket pull request builder" plugin configured, and it * * * * *checks the status of pull requests every minute, everything works fine, it starts builds, BUT after a while (approximately after 5 hours) it just stops running builds.
That is, I create a pool of requests, but the builds on them are not executed.
You just need to restart jenkins. as everything immediately becomes normal, the work continues, BUT not for long, the problem repeats again.
Maybe someone came across?
OS - CentOS
Jenkins ver. 2.150.1
When the builds are working, the logs are something like this (pure vornings):

When builds stop running, nothing is written to the logs at all

Answer 1

See if you have any other pull request plugins running? Specifically the Stash pullrequest builder plugin, try disabling them.

Answer 2

Every minute is too often. Set every 5
