I have been helping customer today to resolve his lockups in production by downgrading from MySQL 5.1.25 to 5.0 We have other customers (and our own projects as well) which run on MySQL 5.1 successfully but I can’t it is on par with MySQL 5.0 stability yet.
This given customer was running MyISAM on FreeBSD with quite basic queries, so may be there are some issues with FreeBSD and MySQL 5.1 still ?
