I suspect that setting debug.mpsafevfs=0 in loader.conf won't help because sysctl shows that it is already 0. Kernel is -current of 2/22 with atamk3l, generic config + IPFIREWALL, IPDIVERT and IP6FWIREWALL, debug is enabled. The freeze, it happened again. About 48 hours uptime, then it froze again. This time, I was away from my desk so the screensaver had kicked in and blanked the screen. When I returned and wiggled the mouse, it did not come back. Neither did it drop into the debugger, or if it did, I was last in X, so I could not see the debugger.

The subsequent manual fsck unearthed significant trashing of a hierarchy of files I was using yesterday. There are now 1764 entries in lost+found! Random sampling suggests that these appear to be files that are part of a large scientific library which I was compiling about 24 hours ago. I note from going back through my syslog that this freeze is always in vnlru; I have 2 GB of mem, and this library I was compiling does consist of lots and lots of files. There may also be a second problem. Note the "lock order reversal" backtrace above showing rawinp and raw6inp in netinet/raw_ip.c:199. This happened both during that boot and on the reboot following the full fsck. -jr On Feb 28, 16:14, Robert Watson wrote: > On Mon, 28 Feb 2005, J.R.
