There is no part of Postgres that would produce a message like "Mutex 22
error".  You need to spend a bit more effort on identifying where your
problem is coming from.  If it does seem to be coming from Postgres,
you need to spend a lot more effort on providing a useful trouble report
if you want any help from the mailing lists.  Please see
