| |
Hello again,
I just got one of those unkillable process. This time it is 'ksnapshot' which hung abnormally. Seeing its state, I'm *sure* it will make the unmount of '/' impossible if I need to shutdown.
As Andreas Bombe suggested, I send some informations about the processes, and if someone needs other informations, I'll try keeping the system running so it can be possible to produce other useful states I'm not aware of.
This system runs a kernel 2.2.9 with glibc2.1.1.
Thanks a lot for your time,
Francois Desarmenien
