Hi
sometimes user space program hangs forever. In old days i remeber there was unkillable dosemu. May be there are good how to. Some one can point to it?
This is problem/solution isn't related to current kernel. This is question: what to do in this sitaution.
Now i have eject(1)
$ ps uax | grep eject root 12662 0.0 0.0 1528 560 ? D Jul31 0:00 eject root 12866 0.0 0.0 1532 560 pts/10 D Jul31 0:00 eject $ date Wed Aug 1 21:56:59 EEST 2007
That same eject worked on that same hardware and kernel before.
# strace -p 12662 Process 12662 attached - interrupt to quit
dosn't show which syscall is called.
kill -9 12662 doesn't help to.
No ops, no other info in dmesg.
How to find problem? How to kill/stop proces without reboot? How to find which lock is taken by kernel to complete user space request/syscalls?
kernel: 2.6.17-gentoo-r4-20061014-00 dmesg: http://89.190.108.145/~rokas/dmesg.txt config: http://89.190.108.145/~rokas/config.txt
Thanks for any hints.
