Hi All, I have one process hung on my linux smp system (2 processors) running RedHat Linux 7. The command % ps -eo fname,tty,pid,stat,pcpu,nwchan,wchan gives the following information about the command : COMMAND TT PID STAT %CPU WCHAN WCHAN rm tty2 21760 R 99.8 - - Is there any way to find out why this particular process is hung and where exactly in the kernel is it hanging ? The WCHAN field does not tell me anything. Also, the stat of the process is always runnable and the % CPU is always 99.8. This process is like this since last 2 days. Thanks and regards, -hiren - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/
