I have encountered a bug in my client’s production environment, in summary we are getting duplicate key value violates unique constraint “act-ru-actinst_pkey” which showed me that there is 2 active tasks running and assigned to the same user here is the exception from flowable engine (Version 6.7.1) :\
I tried to complete one of the tasks using flowable-gui but I get the same error but in the flowable-gui deployment. I noticed that this duplications happens randomly after a mail task and I have many mail tasks in this model, I tried to reproduce this duplication but no success. I thought it could be after a mail sending failure but no success.
Note: I cannot access production environment only backend logs, and I couldn’t reproduce this bug. this client is really sensitive about his data
Ask me for any further specifications and I appreciate any advice or assistance you can provide. Thank you in advance for your help.
