All VM's rebooting for no reason same time every Saturday after Exchange 2010 SP3 Update

Hey Guys

 

I've got an IBM x3650 M2 server running VMware vSphere 4 Hypervisor ESXi 4.1.

I'm running 5X vm's (all server 2008 - DC + TS + Exchange + 3CX + SQL) on it and it had been happily going along until recently.

I had a hard drive go in the raid set about 5 weeks ago. That got replaced by IBM and the raid set rebuilt ok. Everything was stable.

It was about time for me to run some updates, so 3 weeks ago (on a Friday night) I updated Exchange 2010 to SP3 with rollup 6. I also installed the latest windows updates on the 3CX phone server.

The 3CX server didn't like the updates and after the reboot the network card wouldn't connect. A few reboots then it was ok.


I finished everything about 6am that morning. Everything was running well, Went to sleep and woke up that afternoon to a notification that the VM's had rebooted at 2.45pm that Saturday.

I checked the IBM host and that hadn't rebooted, no errors in the logs.

I checked the VMware Console, just had a restart notification in the events. I checked the VM logs from the datastore and it just said the VM's had restarted. Here is a snippit of the logs:

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Last logs from the day before were:

Everything looked ok, so I figured just a random restart.

 
However, next Saturday at 2.45pm the exact same thing happened, at the exact same time!

I waited a week and sure enough at 2.45pm on Saturday same thing.

 
I am at a loss as to what's causing this. I couldn't find any scheduled tasks that might be doing it and if it was hardware I figured the IBM host should be restarting. It's not an overheating issue, we're in winter and the heat sensors on the IBM look normal.

 

It's most perplexing. Has anyone seen anything like this before? What do you guys think might be happening?

 

Kind Regards

Hi,

In the log you posted following can be found:  CPU reset: soft (mode 2)

Which indicates that the Guest OS initiated the reboot...

So I'd definitely check if for some reason all the guest VM's do a reboot on the same time, did you check event logs of the VM's? to see if there is something of interest around the time of reboot? Windows Update (other updates) ... Backup...

Also check your hardware and the following logs for clues

Hey sparvtek

I checked the guest event logs. there's a gap between 2.15pm-2.43pm there. which is strange.

Hey Andrew Hancock

Can I check the vmkernel log from vsphere client?
If i log in I can click on administration, then logs. The logs there only show today unfortunately so I might have to wait until the weekend to see that days log.
it's best to, remotely login to the ESXi host....(console) or remotely via ssh.

if using vCenter Server, you can select File > Export > Export System Logs
Is there anything in the guest event logs about "unexpected shutdown" somewhere around the end of the gap?

Is syslog enabled for the VMware hosts? Might be interesting to see what happens around the guest restarts.

The strange thing is that it happens at the exact same time every Saturday, which makes me think about backup or updates or something. Scheduled Anti-Virus scan maybe??

hi Andrew Hancock

I re-exported the logs successfully but unfortunately it's only showing the last two days. I can't go back to the last Saturday. I'll re-export the logs again just after the reboot this weekend and see what shows up :)

hey guys so I was logged onto the server when the restart occurred this afternoon. I have managed to get more log information. I believe the restart happened at about 2.30pm my time (6.30 UTM time).
I can't see anything obvious in there though as there's a gap in the  logs between 6.30-6.43. :(

I also noticed on the IBM host that the network dropped out at the same time and got a screenshot of that from the management web console.

I'll post and see what you guys think?

Edit: Also note I performed a physical host reboot after the VM's and VMHostClient went down. Just in case it was needed (so you will noticed that in the logs around 6.50ish).

it's so weird, it's always the exact same time each week. spot on 2.30pm on Saturday. It's got to be some scheduled task, i just can't see any *pulls hair out*

just a question, i did have one hdd fail in the first raid set (was raid1), about 6weeks ago. If a drive is replaced in a raid set do I need to perform a rescan on the volume? could that cause this issue?
I don't think a rescan of the raid set has anything to do with VM's rebooting each week at exactly the same time ... It has to be either a schedule somewhere, or something to do with backup maybe ... Scheduled tasks on all the VM's seems unlikely ... vCenter? ...We don't know enough of your setup to give more hints I'm afraid.

do you know where I can check scheduled tasks in the vcenter by ssh login? i don't have physical access to the console.
Login to vCenter Server, and check the Schedule.

i am using vsphere esxi 4.1 and logging in with vmwwareclient , i googled where the schedule should in be vcenter but i don't have that option in my client login. is my version too old, or is that option unavailable for vsphere?
are you connecting to vCenter Server or directly to ESXi ?

i'm logging in from a desktop machine using "vmware vsphere client 4.1" to the ip address of the esxi host.
here is a screenshot of the login and the inventory screen :)

Okay, so you have no vCenter Server, and hence no Scheduled Tasks!
ESXi 4.1 260247 is very very very old!!!!

That's the first GA release in 2010-07-13!

The last version is....

ESXi/ESX 4.1 Patch 11      

Release Date 2014-04-10      

Build 1682698

I would try an upgrade! at least....

and for support you would need to be on at least SP1 of WIndows 2008...

I think you're right.

I've checked pretty much everything.  backup software doesn't look like the cause.

I did find adobe flash update scheduled taskrunning each Saturday at the same time. I just deleted but surely its not that.

One thing I do want to check is the vmkernel.
can I do that from cli with vphere 4.1? When I run the connect command its not recognized. I don't have access to the console as I am  remote atm

Hey Andrew

So I finally solved the reboot issue!
One of the batteries died in the UPS this week so we needed to replace it. We decided to put a new UPS in, since then no reboots!! So the old UPS must have been a bit unstable and was causing the host to reboot. Just so weird that it was the exact same time each week.

I can now sleep easier! :)
