Task completion sometimes fails inside onCompleteReschedule

See original GitHub issue

We’re running db-scheduler on 2 servers, with 1s polling interval and immediate execution enabled. I have about 10 jobs and from time to time some of them fail in the onCompleteReschedule step (5-10 times a day).

Failed while completing execution Execution: task=foo, id=recurring, executionTime=2019-11-14T09:00:00.454264Z, picked=true, pickedBy=bar-567f94488b-jmq9v, lastHeartbeat=2019-11-14T09:00:00Z, version=67910. Execution will likely remain scheduled and locked/picked. The execution should be detected as dead in PT4M, and handled according to the tasks DeadExecutionHandler.

java.lang.RuntimeException: Expected one execution to be updated, but updated 0. Indicates a bug.

Hey folks. I got the same error using PgSQL + lock_and_fetch strategy. Not sure if it’s related to the strategy. PgSQL is just a regular Google Cloud SQL. I couldn’t determine what was going on. What we noticed is that the exceptions happened at times of deployment. If we find any new information, we will share it here.
