Are there any I/O or CPU load issues?
If you don't have any stored procedures that work between them, I'd check
server level limits. MySQL is supposed to be multi-threaded to avoid just
this sort of problem, but if your disk and/or CPU are maxed out (or for
that matter you are out of memory) the whole system may be tied up.
Just my thoughts <warning its a Monday here>.
