Hi folks,
I just pulled up a fresh, powerful, and errorfree server on Debian
woody, with some packages from testing.
When this machine becomes loaded, certain processes become unusable
for a couple of seconds. top shows me this:
19268 madduck 18 0 2208 2208 1076 D 1.3 0.4 0:00 sanitizer
6 root 9 0 0 0 0 DW 0.3 0.0 1:10 kupdated
8457 root 10 0 1156 1156 820 R 0.3 0.2 0:02 top
10843 postfix 9 0 1364 1364 1016 D 0.3 0.2 0:00 cleanup
3156 madduck 0 0 636 636 540 D 0.1 0.1 0:00 procmail
28356 root 9 0 292 288 240 R 0.0 0.0 0:01 supervise
28706 root 9 0 2060 2036 1724 D 0.0 0.4 0:00 sshd
21395 root 15 0 1944 1944 1876 D 0.0 0.3 0:00 zsh
notice the number of processes in ^
uninterruptible sleep mode in this column.
this was after i did something like:
while true; do echo test | sendmail madduck; mailq; done
sure, I am stresstesting the system, but my laptop, which is running
testing/unstable is not showing this behaviour, and its load goes far
higher at times.
what is this an indication of? hardware problems? software problems?
thanks,
