Lightweight processes

[lawsoncs]

Hello,
I have a daemon with 6 lightweight processes, and I want to just kill lightweight process #3. Is there any form of UNIX commands that we can use to kill this specific lighweight process?? Thanks for your help!!

 

[Chacalinc]

could you pls post the exit of:

ps -ef |grep process

did you try: kill -9 pid_of_process ??

Actually, saying THREAD instead of LWP would make more sense. I want to stop a thread (ID #3 when using ps -efL) of my process with a pid of 2236. Thanks!

but did you try kill -9 2236 ? or the pid in the moment..

with killall process you kill all of them, with kill -9 pid you kill only the pid.

Cheers.

When I use ps -efL, all my 9 threads have the same pid, but different thread (or LWP) id #'s. Not at work right now, but I'll post it when I get there later if you would like to see. Thanks.

pls, could you post the ps -efL exit?

Thanks.

Here you go:

UID PID PPID LWP NLWP CLS PRI STIME TTY LTIME COMD
slawson 9794 1 1 7 TS 70 13:32:43 pts/2 0:00 ./my_process
slawson 9794 1 2 7 TS 80 13:32:43 pts/2 0:00 ./my_process
slawson 9794 1 3 7 TS 80 13:32:43 pts/2 0:00 ./my_process
slawson 9794 1 4 7 TS 80 13:32:43 pts/2 0:00 ./my_process
slawson 9794 1 5 7 TS 58 13:32:43 pts/2 0:00 ./my_process
slawson 9794 1 6 7 TS 58 13:32:43 pts/2 0:00 ./my_process
slawson 9794 1 7 7 TS 58 13:32:43 pts/2 0:00 ./my_process

Notice the LWP numbers are different. I want to kill number 3.

I understand now.... I think that you can't do that, it must be done at application level. you can kill with UID, PID, but not LWP.

sorry.
