Well, I tracked this down a bit. Rather easy way to panic -stable box (mine is r279956), but I can't reliably reproduce this. It happens when there is a process running which mmap()+mlock() some file, and while it is running this file is modified on disk (not rm+mv, but open the same file, truncate and write some other data into it). After process exits, system will panic with high probability. So far I got 2 cases: 1) run process which mlock()'s a file; modify that file; stop process and system panics 2) run process which mlock()'s a file; modify that file; stop process [no panic so far]; modify that file again and system panics. Panic message is the same: panic: vm_page_unwire: page <xxxx>'s wire count is zero _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
