I didn’t say it would prevent the crash. it just made sure that subsequent crashes weren’t the result of the first one messing up your filesystem. > rsync from /usr/ports to /export/ports caused another crash. Here is > the backtrace capture: What’s the panic? Judging from the traceback, it is tripping over some assert or test for bogus state.
