So we have been having a few issues with locking up servers so I've been watching show processlist when this happens and it seems that we have a lot of REPLACE INTO sessions(id, a-session) etc.. lines when this happens and when they magically go away everything is running smoothly again. So what are these "sessions" and how do they play with the system? If you show columns from sessions you get to columns: +-----------+-------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +-----------+-------------+------+-----+---------+-------+ | id | varchar(32) | NO | PRI | | | | a_session | text | NO | | | | +-----------+-------------+------+-----+---------+-------+ If I do a select count(*) from sessions I get select count(*) from sessions; ERROR 1053 (08S01): Server shutdown in progress but thankfully the server doesn't actually shutdown! TIPS hints??? usually by the time I contact my support group about it and they get connected 30 minutes to an hour later things are better. Lately if it hangs it is only for 10-15 minutes but at that the librarians are pulling their hair out with 30-40 8 year olds trying to search for a book/check in or out a book!!
