I've got a box that's been running FreeBSD relatively problem-free for the last couple of years. I installed 4.2-R about a week ago, and started having lockups every night. A second box is checking on the problem box once a minute, and logging a message if it famils to connect. I can therefore determine that the lockup occurs reliably a shortly (less than a minute) after the periodic daily run starts. Running the periodic script by hand works fine. So does "make world". I've enabled DDB in the kernel, verified that it worked, then watched the system freeze. However, I normally leave X running on the box, and I got no response from DDB this morning. Am I correct in assuming this is the normal behavior, and I need to shut down X (and probably log out) before the freeze. If that's not the case, and the freeze is locking the system up so hard that I can't get to DDB, any other suggestions for debugging this would be greatly appreciated.
