Could not execute DELETE TimerEntity. Entity was updated by another transaction concurrently.

[Emerald Hieu]

Hi developers,

My app uses Timer Start Event to do some business. I get these errors after restarting JBoss server. I don't have a clue why this error happens. The errors have gone after restarting server 2 times.

Camunda 7.2 JBoss.

Deployment does not provide any case definitions.

Hi Emerald,

Have you observed the behavior a few times or it has occured only once? Could you narrow the problem, so that we would be able to reproduce it?

Cheers,

Roman

Hallo everyone,

I am getting the same error as Emerald and I am using Camunda 7.2 JBoss.

In fact, I have a process A which has a timer every 30 sec and reads from a queue table in the database. Process A has also a sub-process B which make some updates of the database. Once the updates are successful, process B is finished and process A should delete the tuple from the queue. The deletion is throwing the following exception:
