Folks I suck a lot of things and performance issue is one of them.
After upgrading from 5300-06-03 to 5300-12-04 we started seeing an issue with some runaway processes. It varies as some of these processes have a TTY accociated with them and some do not. If you could give me any idea of what to look for it would be most appreciated. I did contact IBM support and provided a perfpmr but all I have so far is your machine is CPU bound and here are the top processes contact your applications people. Well I kind of already knew that. Just expecting some guidance on what might have changed to cause it.

Looking at specifics about the processes being run by this user.
There have been no new processes spun off by the main initmenu.42r process since yesterday at 13:39. I am thinking the user still has the session open on his/her computer but what is it doing to use that much CPU.
The second scenario with no TTY associated with the process looks like this.

not too long ago, i wrote a very short script that will bring up 4 customized xterms. The script went completely abnormal simply because of an error I had made in a while loop. This script took control of the system and rendered everything useless. The system admin team which i was part of... (4 Replies)
I got about more than 300 emails from root with the subject "Runaway processes killed" saying that "13146 12737 97.7 6 bash" . So what should I do? Any help would be appreciate (2 Replies)
Is there a way to monitor certain processes and if they hang too long to kill them, but certain scripts which are expected to take a long time to let them go?
Thank you

Hi
Is there an easy way to identify and group currently running processes into OS processes and APP processes. Not all applications are installed as packages.
Any free tools or scripts to do this?
Many thanks. (2 Replies)
Hello all,
My hosting provider has contacted me in order to notify about a runaway process issue. Here it is:
They have given me a list of those processes but I can neither analyze nor understand what I should do.

I had issues with processes locking up. This script checks for processes and kills them if they are older than a certain time.
Its uses some functions you'll need to define or remove, like slog() which I use for logging, and is_running() which checks if this script is already running so you can... (0 Replies)
