Hi Gurus,

In some of our servers, adb is getting invoked automatically causing large amount of cpu resources.As I can't see any cron job, would there be any system/hardware issues?
Thanks in advance

I've never heard of this. Adb is a debugger used to either tune the HP-UX kernel or debug applications, core dumps, etc. Are you able to track down the parent process of the running adb process and figure out who/what launched adb? Can you get the full syntax of the adb command? Is someone tuning a specific kernel tunable and that is eating up your CPUs?

What Dave said. Plus, when you see that adb has "taken over" your system, issue the command

ps -efx | grep adb | grep -v 'grep adb'

This should show you all of the instances of adb currently running, by whom, and if interactive from which pty/tty. At the very least, take the second column and search for those processes - those are the parent process(es) of your adb's. Keep searching for parent processes until you've determined who your "culprit" (or "culprits") is (or are).

Kill it, it doesn't deserve to live. :-)

You don't get out much? :-)

There are two other threads that mention adb being piggy:

>Mike: ps -efx | grep adb | grep -v 'grep adb'

You can improve this by:
UNIX95=EXTENDED_PS ps -Hfx -C adb

And as mentioned by Mike and the other threads, find out the process tree, using above -H.

Dennis - I get out as little as humanly possible. :)
