[BlueOnyx:07049] Re: web1.uhostme.com Yum Update output for 04-10-11

[Darrell D. Mobley]

Well, the experiment failed.  It seems no matter how many times I reboot the server after a new kernel comes in via YUM and I edit grub.conf, changing “default=1” to “default=0”, it hangs in the middle of the night, stops listening on HTTP, FTP, SSH, etc. With monitoring enabled, my colo host saw it stall at 3:33AM and power cycled it.  It sure would be nice to figure out WHY this is happening because I had power cycling that six drive RAID5.  The only clues I can come up with now are:

 

Apr 10 06:06:23 web1 init: Trying to re-exec init

Apr 10 06:06:32 web1 init: Trying to re-exec init

Apr 15 03:12:59 web1 init: Trying to re-exec init

 

The 10th is when the big YUM choke came through, bearing a new kernel.  And of course, last night I edited grub.conf to change default=1 to default=0.

 

Of course every 30 minutes, it’s trying to clear out those 44 failed logins and failing, because they keep reappearing in the GUI.

I had not rebooted, but I have now.  Twice. J

 

Why you might ask?

 

It’s an experiment.  My HP DL380 G3 likes to hang up at 4AM on the morning after a new kernel comes in via YUM and I edit grub.conf, changing “default=1” to “default=0”. After it hangs up, if I reboot it, it runs fine until the next time a new kernel comes in via YUM and I edit grub.conf again to change the default kernel to the newest one.  I don’t know why.  (By hang up, I mean it stops answering HTTP, FTP, SSH, etc., but responds to PINGs fine.  So it’s not locked up, it just quits responding.)  

 

So my experiment tonight is to change the default kernel to the latest “0”, reboot it, and then reboot it again.  I want to see if the second reboot up front will work the same magic it has in the past, just  without it sitting 5 hours waiting on me to get up and cycle the power strip.

Hi Darrell,

You can remove /etc/cron.daily/tmpwatch.rpmnew

Did you reboot since installing all updates? If not, please do. A lot of processes don't like it of glibc or other libraries are replaced while the services are still running.
