We are a mixed MS/Mac/Linux shop (mostly MS, and I'm an MS admin) and added 18 Macs to the K1000 a few months ago.  They have since stopped responding and this appears to be related to the konea process stopping intermittently, sometime between 2 and 37 minutes after starting.

Here's the timeline of events:
  • Added Macs to old ds-kace01.domain.local, everything checks in consistently, no issues.
  • Added DNS entries to point to kace.domain.com.
  • Ran this script to change Macs over to new hostname: (http://www.itninja.com/question/script-to-change-kace-appliances-for-mac-amptools).  Specifically, this (yes, my reading comprehension sucked that day; I should have read chucksteel's comment first):
#!/bin/bash
# redirects a KACE client to pcckboxdev - rgetter 070215
cd ${0%/*}
mv -f amp.conf /Library/Application\ Support/Dell/KACE/data
# restart the AMPAgent
/Library/Application\ Support/Dell/KACE/bin/AMPTools stop
/Library/Application\ Support/Dell/KACE/bin/AMPTools start
  • Macs stop reporting.  PCs continue to report.
  • Changed hostname on K1000 to kace.domain.com.
  • Research further, noticed I missed chucksteel's comment, and also received heads up from Kace support.  Disabled the first script, then ran this script manually on all Macs.  Verified that amp.conf and amp_auto.conf were updated to point to the new (correct) K1000.
    sudo /Library/Application\ Support/Dell/KACE/bin/amptools -resetconf host=kace.domain.com sudo /Library/Application\ Support/Dell/KACE/bin/AMPTools stop sudo /Library/Application\ Support/Dell/KACE/bin/AMPTools start
    • Macs still not reporting in; notice that the konea agent is not running.  Run sudo /Library/Application\ Support/Dell/KACE/bin/AMPTools start to start the AMPAgent and konea processes and a given Mac will report in and update inventory; however, after an intermittent period of time (shortest has been 2 minutes, longest was 37), konea stops and the Mac goes "offline" again.

    I've been researching the three error codes (EXC_CORPSE_NOTIFY, EXC_I386_GPFLT, and EXC_BAD_ACCESS (SIGSEGV), but haven't seen anything yet that makes sense to me.

    • One other thing I forgot to add. I did eventually try uninstalling/reinstalling the Kace Agent to see if that helped, and it did not; the behavior continued with that machine.

      Also, we purchased another (brand new) Macbook Air some time after this all occurred. With a fresh install where kace.domain.com was (correctly) designated as the host, this issue is still occurring.

      Kace tech support has been focused on the Macs, but I'm wondering if there is anything on the K1000 which might have been reconfigured incorrectly?

    FYI to all, in the event anyone finds this at a later point; the issue turned out to be a script that was still enabled to run every 30 minutes on the Macs which reset amptools.

    After disabling the script, the issue went away.

    File this under Stupid User (admin) Mistakes.

    I really gotta stop smoking crack... :D
