We had a job running when during that time the MySQL server went away (and restarted soon after) but this resulted in a runaway job which when trying to 'stop' it, resulted in the NPE:
Build Date: 21 Nov 2019
Stack Trace: is too big, thus linked here
So how to we kill the running job now without restarting bamboo entirely?
What you observe is most probably the data integrity issue caused by MySQL outage. The build cannot be stopped because there's nothing that should be in fact stopped.
IMO restarting Bamboo Server is the best course of action.
Thanks, seems like the best way to go indeed.
After restarting bamboo itself, everything was back to normal. The weird thing is though that before restarting bamboo the other pages still kept working (or atleast seemed to have recovered)
Ow well, let's just chalk this up to a mysql outage and just restart bamboo
