Just a brief post today. Back in the start of January we saw and older Server 2008 32-bit showing this error in the title. It would spam the alert in the event log of the server until it became inaccessible. Not much was to be found about the error but I did find this post from Alex575 who also saw the error in January.
As no answers had been made on the post I decided to follow it and try and work out a solution. We haven’t updated ESXi and Tools above 9359 since ESXi 5.5 U3 so I started thinking that maybe the new VMware Tools 10 package could solve the issues as the event log entries came from the Tools service (vmsvc).
We upgraded the servers tools version to 10245 (Version 10.0.5) and from crashing every 10 days it has as of yet not crashed (14 days and counting).
VMware Tools from Version 10 will ship outside of vSphere releases as blogged by Brian Graf here: https://blogs.vmware.com/vsphere/2015/09/vmware-tools-10-0-0-released.html
The 10.0.5 release can be downloaded here: https://my.vmware.com/group/vmware/details?downloadGroup=VMTOOLS1005&productId=491
