Sowmya Ramesh commented on FALCON-1068:
---------------------------------------
[~kawaa]: Can you confirm if retry is attempted or not? By default retries is
set for acquiring lock and write attempts. It will be good to find the root
cause but as I said from code walk though onDelete no graph operation is done.
So I am not sure who is holding the lock. If retry is not attempted we should
add the retry logic.
{code}
default storage.lock-retries is set to 3 and storage.write-attempts to 5

> I have a simple script "manage-entity.sh process dss" that deletes, submit
> and schedules a Falcon process.
> A couple of times per week, I get the "FalconCLIException: Bad Request;Could
> not commit transaction due to exception during persistence" when submitting
> the process.
> The workaround is to restart Falcon server...
> e.g.:
> {code}
> $ ./manage-entity.sh process dss my-process.xml
> falcon/default/my-process(process) removed successfully (KILLED in ENGINE)
