Mar 14, 2011-How to deal with NXDI orphan processes Mar 14, 2011-How to deal with NXDI orphan processes Deleting “Orphaned” processes will free up system resources because they are using machine CPU and memory. An automatic cleanup script has been implemented to identify all orphan processes and they will be terminated by the 2nd line helpdesk one week after the informed email. You can use the following orders to identify those processes and kill them if you want. 1. You can look at the email sent to you. They will tell you the clustername, hostname, user id(wbi), pid(process id) 2. If you want to identify the lsf-cluster name, type “lsid”; 3. If you want to know which host you are on right now, type “hostname”; normally you are on the other host. 4. Type “bsub –I(capital i) –m $MYHOST xterm & Notes: for example, the orphan process is running on “apc7007”, but right now you are working on “apc7002”. Then type “bsub –I –m “apc7007” xterm &”; don’t forget the notation mark “”. 5. In the new “xterm” window, if you want to verify your processes, please type “ps –fu nxp27399” or “ps –elf | grep wbi”. 6. The last thing is - if you want to kill them by yourself, type “kill -9 pid” or you can use “fuser wbi”. But fuser may result in some bad things and it seems only to be allowed to use by root. So “kill -9 pid” is strongly recommended for end users. Just for reference.
