service-api gets unhealthy state after postgresSQL deadlock

[qasamppa]

I am not sure, if this is correct place for this issue... Suddenly service-api noticed postgreSQL deadlock while updating test-results. What might cause this?
We have docker solution in use and latest docker-compose.yml without modifications
Only change we made was this elastic search data folder group and rights change based on ReportPortal documentation. This was mandatory.
