The patch in question is at www.freebsd.org/~jhb/patches/witness.patch It will print out message to the console 'dead witness: foo' where foo is the lock category name when witness objects die (though only the first time that a given object dies). If you see the same witness die multiple times let me know. The only witness I've seen die so far in general use is the pipe mutex witness object. -- John Baldwin <jhb@FreeBSD.org> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
