The problem is the MySQL (by default) uses name resolution extensively. But the resolver calls are not thread-safe on FreeBSD. Race coniditions exist that can cause odd cicumstances which result in MySQL thrashing a bit. > 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.

This problem doesn't exist on other platforms. Jeremy -- Jeremy D.
