Ok, we know that FreeBSD has problems with its thread implementation; however, I'd like to know if the MySql guys know exactly what causes the problems to which Mr Zawodny refers.
I'm running FreeBSD 4.6.2, and have seen the 'rogue thread' problem before which leads me to believe that either FreeBSD has not addressed the problem or MySql hasn't. To be fair MySql says in its documentation that FreeBSD is not recommended because of its threading implementation. Furthermore, I wonder if anyone has been working with MySql and FreeBSD 5.0 DP1 and, if so, what behavior they've experienced.

We have a new project using this MySQL engine, with lots of inserts/deletes. But it happens that in the mornings, when nobody makes any kind of access to the database, we still have a MySQL daemon eating up 99% of CPU. If I log in as 'root' to the mysql server and make a 'show processlist', the only process in the 'query' command is mine ('show processlist'), all the others are in sleep mode (with NULL info). Is there any periodic maintanance/optimization work that the mysql server is doing? If so, why does it take so long? Can I schedule it sometimes during the night (and if so, how?)
