Hi,
We are currently having some intermittent problems where our RT stops
responding. I have isolated this I think to a database problem of some
sort. I turned on Slow Query logging and this is what MySQL picked up. Any
ideas what may cause such performance issues. It is intermittent but very
annoying when it does occur. I have tuned the DB with mysqltuner and when
it does run proper then it really hums along.
# Time: 090317 12:42:29
# User at Host: rt[rt] @ localhost []
# Query_time: 11 Lock_time: 0 Rows_sent: 1 Rows_examined: 0
SELECT GET_LOCK('Apache-Session-288c54fb38d789956edc518ca4321abb', 3600);
# User at Host: rt[rt] @ localhost []
# Query_time: 11 Lock_time: 0 Rows_sent: 1 Rows_examined: 0
SELECT GET_LOCK('Apache-Session-288c54fb38d789956edc518ca4321abb', 3600);
# User at Host: rt[rt] @ localhost []
# Query_time: 11 Lock_time: 0 Rows_sent: 1 Rows_examined: 0
SELECT GET_LOCK('Apache-Session-288c54fb38d789956edc518ca4321abb', 3600);
