 |
|
About a week or two ago I did a full "emerge world" and caught my dual opteron server up to date. A few days later, my server wasn't responding, and so I had the datacenter do a reboot, which brought it back online. About 4-5 days later, I was logged into the system and noticed that there were 10 or so sh processes in top that were taking 100% of both CPUs. I rebooted the system and they were gone. Today, which is about 4-5 days after I last reboot the system, I logged in and noticed there are currently two sh entries sharing 100% of both CPUs. I have no idea what is spawning them, or what they're doing. Here are the entries:
| Code: | PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
29351 root 25 0 4436 588 452 R 99.9 0.0 777:13.75 sh
29360 root 25 0 4436 588 452 R 99.9 0.0 778:06.79 sh
|
Here's output from ps -C sh -f:
| Code: | root 29351 29348 99 Oct29 ? 12:58:17 /bin/sh -c (hostname)
root 29360 29357 99 Oct29 ? 12:59:10 /bin/sh -c (hostname)
|
Anyone have a clue what this is coming from or how I can track this down? |

Have you checked the parent processes (29348 and 29357) with ps -f?

No idea where it's coming from, the PPID should already give you a hint. If this doesn't help, you could try a few other things:
hook a debugger to one of them or check what files it's using with . |

| Thanks for the suggestions, guys. I killed them after making this post, and they haven't come back yet, but as soon as they come back I'll check the parent processes and the debugger. |
