Intermittent Freezing / Pausing of VMware ESXi 4.x on HP DL360G7

Hi,

One of our VMWare servers has become exceptionally slow and unresponsive, this is due to it 'pausing' at regular intervals.  Everything stops, everything becomes unresponsive for a minute or two…and then carries on.

It was happening every 15-20 minutes for 1-2 minutes, now it is happening far more regularly following 9.2b firmware install.

Please see image – anybody seen anything like this before ?

Thanks

Only NIC adapters were requiring update... in auto procedure so I let it do that.
I have just finished running 1hr of Smart Start (all) tests with only green results,

So I can only assume it's either the VMware media drive or something, perhaps with the iscsi softwate initiators within the vmware configs.
Really I need another VMware drive, may have to see if HP can ship one out...

What is it reporting on your events and arlams?

Is it a memroy issue, CPU or misconfgured policies?

Free Tool: Port Scanner

Check which ports are open to the outside world. Helps make sure that your firewall rules are working as intended.

One of a set of tools we are providing to everyone as a way of saying thank you for being a part of the community.

No errors, no alerts.  All CPU / DISK and other real time performance data exhibits issues above on image and whilst accessing VM's they stop / start / pause.

User side experience is just SLOW, but SQL querires and other scripts time out

It's maddening

Using VMware Infrastructure  (VI) Client, connect directly to the ESXi host experiencing the issue. Log in as  root.
      Note: These steps can be performed using an Administrator account logged into the VirtualCenter Server as well.

Click the Configuration tab.

Click the Advanced  Settings link.

Navigate to the Misc Category.

Find
      the Misc.CimEnabled parameter from the list and change the value
      to 0.
      Note: The default value of Misc.CimEnabled is 1.

Click OK.

Restart the ESXi host for the change to take effect. This change is persistent across  reboots.


I got this infor from the following:

how new is the implementation?

Misc.CimEnabled, sadly doesn't exist - but the KB's relating to that seem to describe purple screens and lockups rather than this weird pausing.

The server was installed into an active VCenter Solution about 6 months ago and has been workling flawlessly until this weekend, no changes or reconfigurations made - just got note from SQL man that overnights were timing out...

On a whim I disabled the software iscsi initiator and perf logs then fine.... have removed all discovery points and re-enabled - will then add targets one by one.  Sods law it'll all come back no problem! Grrr

Zach2001Author Commented:
Re-enabling the iSCSI adapter and adding all the targets one by one showed that on addition of one of the targets the problem re-occurred. I rebooted the adapter at the SAN end and all has been great since.  Have verified paths and that path is active and causing no issues... weirdly is wasn't causing issues with the other servers either.
I am happy, but somewhat befuddled.

A Mystery. No errors on SAN either.  Will replace cable when next on site.
