[...] There was an pf-related issue that require to use mpsafenet=0. Is it solved now? >From pf.conf(5): Due to a lock order reversal (LOR) with the socket layer, the use of the group and user filter parameter in conjuction with a Giant-free netstack can result in a deadlock. If you have to use group or user you must set debug.mpsafenet to ``0'' from the loader(8), for the moment. This work- around will still produce the LOR, but Giant will protect from the dead- lock. Unfortunately I have no machine available to test it. Regards Björn
