Cause: logconv.pl did not handle server restarts very well. When the server restarts, the connection counter is reset. Any data associated with the old connection number is lost.
Consequence: Some statistics are not calculated correctly or at all if logconv.pl detects a server restart.
Fix: Index statistics by a tuple of (restartnum,connid,opid) where restartnum is the Nth restart, connid is the connection ID during that start period, and opid is the ID of the operation on that connection.
Result: All statistics are calculated correctly no matter how many server restarts are detected by logconv.pl
