An installation (using Oracle DB) has been upgraded from 6.0.1 to 6.0.8 and an error started to be logged after a few minutes:

The error repeated ~100 times per a day.
Debug level for task manager was increased and here are 2 files where we see when it happens. I've added empty lines just to split blocks/function call, all lines are present and in original order.
Its known that there is some scripts that close certain problems, including the *** problem shown in the logs. They do an event.acknowledge API call.
My findings:
in each file (in each cycle) task manager tries to close 2 or 3 tasks, for the same trigger. 1st (and next one) task/attempt of closing is failed with the error, while last one is without the error.
