See http://www.freebsd.org/doc/en/books/developers-handbook/kerneldebug-deadlocks.html for instructions on what information to collect. If you can provoke your problem with using WITNESS that would probably be great, but it will slow down your production machine noticeably. When WITNESS is enabled you might also get more information - such as LOR warnings, which you should also collect. Keep the dump file, someone might ask you for more information. Good luck!Received on Mon Nov 02 2009 - 23:23:03 UTC
