devmon goes purple
list Dirk Kastens
Hi, it seems, that this very old problem occurs again. I wrote a mail to devmon-support, but didn't get an answer. We are using Xymon 4.3.27-1.el6.terabithia on Scientific Linux 6.7. Everything was running fine until the latest kernel update to kernel-2.6.32-642.el6.x86_64. After that, devmon stops working from time to time. The processes still are running but all devmon tests go purple until I restart devmon. There's no entry in the devmon logfile. Does anyone else have the problem? Regards, Dirk

Used to happen to me also. I think I ended up having a cron job test, kill
and restart. But that was a long time ago, and it hasn't been a problem
for a while. Sorry I can't help other than to confirm it's not just you,
and also happens with older kernels.
It might not be the kernel that did it. You'll have rebooted to get the
new kernel running, so it could have been caused by any other effect of
rebooting. For instance, the fault might have been triggered by simply
stopping and starting devmon. If you're at liberty to boot back to the
previous kernel, you might find it still has problems.

Hi Jeremy, thanks for your reply. So I'm not alone ;-) The following packages have been updated: Jun 17 05:23:34 Updated: kernel-firmware-2.6.32-642.el6.noarch Jun 17 05:23:36 Updated: ntpdate-4.2.6p5-10.el6.1.x86_64 Jun 17 05:23:37 Updated: ntp-4.2.6p5-10.el6.1.x86_64 Jun 17 05:23:37 Updated: ntp-perl-4.2.6p5-10.el6.1.x86_64 Jun 17 05:23:52 Installed: kernel-2.6.32-642.el6.x86_64 Jun 17 05:23:55 Updated: kernel-headers-2.6.32-642.el6.x86_64 On Jun 17 at 06:31 devmon stops for the first time and after that every one or two days. Even after rebooting the machine. Meanwhile I created a script in cron.hourly that restarts devmon every hour. But I wonder why this happened immediately after the update.
