killall -STOP xclock... hangs filesystem

killall -STOP xclock... hangs filesystem

Post by Colin Hirsc » Thu, 07 May 1998 04:00:00


I am using kernel 2.0.33 on a P55C (P166MMX) with something that was a
RedHat 3.0.3 some time ago.

In preperation for playing an animation under X I "killall -STOP"ed the two
xclocks and one xosview running on the machine (this I did as
root)(paranoia mode -- I want smooth playback).

I had no problem with the animation, but then, completely independent, I
tried to copy some file around (as normal user) but got a "file too large"
error. The copy operation left the destination file empty (source was like
3kb and there were still enough bytes free left). I then tried to do a
"echo hallo > ttt", to no avail. A file ttt was created, but left empty
again. The same happened on other partitions...

After completely killing the stopped tasks everything worked as normal
again. I have yet to reprocduce this bug. It is not the first time that I
kill -STOP processes for some reason, but the first time such a strange
behaviour has occured -- at least I can't explain it.

1. killall -CONT & killall -STOP

Is there any explanation why killall -STOP is NOT pausing the process,
but killall -CONT is stopping it?

When I type 'killall -STOP mpg321' nothing happens. When I type
'killall -CONT mpg321' it says:

And I can't get it to play again.

Any ideas why this is happening? Do I need to fork something?


2. external terminal on serial port and login

3. Quick stop/start Filesystem ?

4. Installation of 101318-54 on dataless machines

5. dump0.3 stopped working for one filesystem since april

6. Wanted: FAQ sheet, ftp sites, book lists, software

7. Stop user seeing rest of filesystem

8. Is anyone else's boot drive sticking, or is it just me?

9. What would stop a filesystem name???

10. Load stops with VFS: Mounted root (ext2 filesystem) readonly

11. Hang, Hang, Hangs. No hopes!

12. ntp stopped working, hangs connections
