Stan, Thank you for your reply. It is my own daemon( I wrote it by myself) and do not know why it changes the STAT.
I found out that STAT field is D for Uninterruptible sleep (usually IO) R for Running or runnable (on run queue) S for Interruptible sleep (waiting for an event to complete) but what does Uninterruptible sleep means? And what is it caused by? Can anyone explain that problem? (When STAT is D for the daemon , the daemon does not seem to run ) Thanks L. > exp...@hope.cz put forth on 4/16/2010 5:23 AM: > > I have a daemon running on my Debian ( Lenny) box.When it is started , > > I check the process state ( by ps -ax command) and I can see in STAT column > > S > > letter and the daemon works as it should.After some time, the STAT is > > changed to > > R but the daemon still works OK.But after few hours the STAT is changed to > > D > > letter and the daemon does not work properly.It seems as if it is stopped > > running eventhough it is among the list of processes. > > Can anyone explain that please? > > Which daemon? > > -- > Stan > > > -- > To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org > with a subject of "unsubscribe".
