Reopen Issue

When running multiple parallel builds of Kiwi, sometimes we get this error

<class 'psycopg2.extensions.TransactionRollbackError'>: deadlock detected
DETAIL:  Process 3844877 waits for ShareLock on transaction 164249560; blocked by process 3761645.

I can't see whole request here, but assume that it was kiwi-build without explicit --release option. This should be possible workaround as I assume that getNextRelease returned same value for two tasks.

Can you check hub log for where it exactly happens?

I've played with it a bit and it is a corner-situation which was not fixed by original #788. Created #3721

Which koji instance is this happening in? How often does it happen?

Do we have a full hub-side traceback?

The issue happened on our private Koji instance. Sadly as it was 5 months ago, I'm pretty sure it happened after that couple times but these days we are not building images that often so I don't have any recent logs with the issue… =(
