Error ENGINE 03005

After update camunda from 7.8 to 7.9 and apache tomcat 8.0.47 -> 9.0.5 I tried to execute step on my any deployment with timer. I received error:
An error happened while claiming the task. :ENGINE-03005 Execution of ‘UPDATE TaskEntity[]’ failed. Entity was updated by another transaction concurrently.


Could you please share your process and the complete stack trace of the exception.

Best regards,

I’ve solved this problem yet
jobExecutorActivate property in bpm.platform should be true, it was false. Thank you :slight_smile:
