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.
