Activity Manager - tunmgr

Other users say that this process is related to the Blackberry app. See > https://discussions.apple.com/thread/4957570?start=0&tstart=0

As mende1 said, it's a Blackberry process, do you have a Blackberry?

How do I delete a process that's running in the background?

Just realized that I linked the same thread as mende1.

You're welcome.

I had the same problem and researched it. The tunmgr is essentially a bug that spawns a looped process due to checking the "Open Blackberry Link when a device is connected" in Blackberry Link. To stop the process, open Blackberry Link -->> Preferences (not in the main menu, the gear in the top right corner) -->> uncheck "Open Blackberry Link when a device is connected". Then restart and it should be back to normal.

ps - thanks for fixing this Blackberry!

well how do I uninstall the blackberry thing cause I dont know how.

Read the link of my first reply

Here's another, that doesn't involve removing the BB software or changing its settings. Since the program hangs on a reliable basis, just look for it using a lot of CPU time and kill it when it is:

#! /bin/sh -

cpu=`ps aux | grep -ie tunmgr | grep -v grep | awk '{print $3}'`

if [ $(echo "$cpu > 50" | bc) -ne 0 ]; then

ps aux | grep -ie tunmgr | grep -v grep | awk '{print $2}' | xargs kill -9

fi

The program looks for "tunmgr" and kills tunmgr if it is using more than 50% CPU when the program runs. Put it in a crontab that has administrator privileges set to run every 1-5 minutes and tunmgr won't eat your battery again.

Mende, excuse my ignorance, but could you please explain step by step to a complete rookie how to "follow the path" in Terminal and how to go about deleting the related Folders and Files ? Just want to delete everything that has to do with this app that is now driving my cpu insane. thanks so much !
