Just to add something: I am suffering from a deadlocking freeradius too,
but I don't use anything related to mysql, just LDAP. (On Debian Sarge,
compiled into a DEB using a clean chroot.)

After some unknown amount of time or after a (yet) unknown request the
daemon locks up using 100% cpu, a strace shows a constant flow of segfaults.

I don't know if this is related to the bug you are seeing, but it seems
like it.
