java.sql.SQLException: Transaction was deadlocked
The below fix should help resolve this error if you encounter it:
YF:2016-07-23 17:33:03: ERROR (DBAction:doSelect) - Error occured
selecting data: java.sql.SQLException: Transaction was
deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction.
This one doesn't pop up very often, but here is a forum post that should help clear this up!
The short of it is, running the following SQL against your configuration database should resolve this (back up the DB first!):
Where <Database> is the name of the Yellowfin database.
Please note. You will need to restart YF after making this change.
