Flagging fault Answered
I tried to flag some flag some spam forum topics. The first couple of times the response was very slow.
The third topic I flagged, I did not get the message confirming the flag, I got this instead:
500 -- error: org.hibernate.exception.GenericJDBCException: Could not execute JDBC batch update
(Possibly temporary fault - five minutes later, all is back to speed, no more error messages)
