We're running 3.0-RELEASE on a few dual P-II boxes. Occasionally, processes will start getting hung in 'D' (disk-wait, IIRC), even on an otherwise-idle machine. They never come out, they aren't kill -9'able. Once the system gets into this state, commands like 'df' and 'ls' are likely to go into disk-wait. Eventually (on the order of minutes/hours), something crucial like nfsd, ypbind, or sshd gets stuck in D, and the machine requires a reboot. I can reproducibly force the cascade of D problems by running an a.out Netscape -- it gets hung after <2 CPU seconds, and things go downhill quickly. But I believe the problems have occurred before without the use of any a.out executables. Has anyone else seen this?
