This seems to have started happening recently, perhaps after my last reboot. Offhand I'm not sure if I changed kernels at the time, but thats definately possible...
Created attachment 91154 [details] top -b -n1 output
same thing has happened to me, kernel 2.4.20-2.48smp and glibc-2.3.2-27.9
Its very strange that all TIME field are zero. That would seem to indicate that both utime and stime are zero. Can you paste in /proc/$pid/stat for some process when this happens? Also, are you using LD_ASSUME_KERNEL or anything strange thread-related?
/proc/pid/stat works: 11278 (slurpcpu) R 11257 11278 11102 34834 11281 0 20 0 60 0 1180 0 0 0 25 0 0 0 84160728 1380352 58 4294967295 134512640 134513592 3221218944 3221218864 134513412 0 0 0 0 0 0 0 17 0 1180 0 0 0 11278 (slurpcpu) R 11257 11278 11102 34834 11283 0 20 0 60 0 1538 0 0 0 25 0 0 0 84160728 1380352 58 4294967295 134512640 134513592 3221218944 3221218864 134513412 0 0 0 0 0 0 0 17 0 1538 0 0 0 11278 (slurpcpu) R 11257 11278 11102 34834 11285 0 20 0 60 0 2047 0 0 0 25 0 0 0 84160728 1380352 58 4294967295 134512640 134513592 3221218944 3221218864 134513412 0 0 0 0 0 0 0 17 0 2047 0 0 0 I do use LD_ASSUME_KERNEL on threaded applications which need it (Mozilla, Python etc.), but not on the system as a whole.
Ah, I see what's happening. Thats not the final RHL9 kernel. It doesn't have the &P->rtprio, &P->policy, fields in /proc/$pid/stat, so the fields added to stat in that kernel version are incompatible. You need to upgrade the kernel.
