Hi Alex,

This is a well known bug.

You should consider to use linuxthreads. I hope it will be usable
for 4.8R. Else look for patches at http://people.freebsd.org/~mbr/patches

I run now all production servers with linuxthreads and hangs have
gone.

This document here describes the main problems with mysql on FreeBSD
linked with libc_r:

Short version of problems with native threading support (userland threads):

1. Non-thread safe DNS Lookups
2. Unfair Scheduling
3. High Load
4. No SMP Support
5. Missing Locks
