Hi,
I have a VM that keeps freezing at random times. Its never under heavy load and is a decently resourced VM. After i completed a datastore migration i have these freezes. 6 other VM's are on the same datastore and host with no issues. The freezes show no error in windows or in vsphere logs.
Any ideas what it could be?
there has to be some information in the vmware.log of the vm. or hostd and vmkernel logs of the host.
if you can share the three for the timestamps the issue occurs..
Thanks for the reply.
I went to get the hostd log and realised i didn't setup a location on the new datastore to point the host logs to. Usually vsphere would throw and error along the lines of "logs not saved on persistent storage". For some reason in this instance i didn't receive any such error so i didnt know.
Anyways i have set this up now and log files for the hosts are being collected on the new data store so i might have to wait a few days to gather some data.
the vmware.log file should be available in the vm directory .. share the same if you can
Bump, any chance someone could help me with this issue, im a little stuck and this server continues to intermittently freeze. Log files have been attached.
Can you upload a fresh set of logs (vmware.log [for the VM], hostd.log, vmkwarning.log and vpxa.log) and also a time when an example freeze occurred?
My findings from the log files you provided-
veem snapshot consolidation jobs is freezing the VM, refer to the following screenshot.
You are running ESXi 5.0 version and there is a hotfix available to resolve this issue-
Permanent fix-
Install hotfix VMware ESXi 5.0, Patch Release ESXi500-201408001 (2080838)
Description of the known issue-
This issue occurs if the virtual machine generates data faster than the consolidate rate
You can also workaround until you patch the VMhosts

Hi Deepak,
Thankyou for your reply.
There was no such parameters as snapshot.maxConsolidateTime or snapshot.maxIterations. So i have created these parameters and set the values as you have explained. I will let you know how this goes.
Also i am unable to find vmware update manager for 5.0 under vmware downloads to install the patch. Was this named something different before, are you able to assist me in finding the installer for this so i can download it.
Hi Deepak,
The workout around provided didnt work. Still getting the same freezing issue. Although like i said i didnt have those parameters, i thought hopefully adding them in manually would work.
VMware has also provided hotfix as a permanent fix, is it something which you can plan?
Can you send the latest logs (Vmware.log & vmkernel) files.
I would like to complete the hotfix (patch) but as i stated in previous reply i am unable to locate the vsphere update manager. Vmware is notorious for changing their names of their products but leaving documentation with old names so anything i search for in downloads as "update manager" i am unable to find anything.
I need the update manager installed so i can complete the patch (hotfix).
Can anyone help me with this? im still stuck on this issue.
