vmware tools update, delay reboot

When we patch our vm hosts, and tool updates are available I will update the tools on the guests using the advanced options
/S /v"/qn REBOOT=R" to suppress the reboot.  Then the guests will be rebooted when they get Microsoft patches.  The delay for rebooting this particular guest was 18 days.  I have been doing patching this way for several years and have not had any issues.  This was on a Windows 2008 R2 server.  

Has anyone seen any issues when delaying reboots from tool upgrades?

Are you having issues?  If not, there is no issue I know of delaying the reboot for VMware Tools. They assist video, file sharing, mouse and such like. Delaying the restart should not cause issues.

I am not saying the reboot delay of the tools caused an issue.  My boss believes it was the cause.  I do not believe that the tools caused the issue.  We have a server that uses sftp to download a file and it did not work this AM.  This was the error in the event log.

 IO::Socket::INET: connect: An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full. : 0

So I am just trying to look for a cause....other than the tools ;-)

Do the tools help the guest manage memory?
JohnBusiness Consultant (Owner)Commented:
Memory is managed by the settings, not the tools. I don't think VMware tools are your issue. The only way to clear them from doubt is to update Windows, restart and see,

If your organization has a need to mass-create AD user accounts, watch this video to see how its done without the need for scripting or other unnecessary complexities.

We do not do it that way, we do not combine VMware Tools updates, with Microsoft Patches.

We Update VMware Tools, and restart in a scheduled downtime Window, and then later update Windows Patches.

So we know which broke the VM. We have had issues when combining all into one reboot.

There is a memory management driver in the VMware Tools for VMware vSphere, this is how the balloon driver is managed! Sometimes it has been known for this driver to hold onto memory.

I agree with Andrew on separating the reboot times - my method as well.

So at this point, you cannot know. I do not think Tools are your issue, but there is now way to know so all you can now do is restart and see what happens.

Thank you both!  Yes we rebooted the server and it corrected the download issue.  Perhaps we will separate the two tasks going forward.
