Any help ?

Thanks

Hi,

Did you ever get anywhere with this?

It's come to my attention I have three servers logging this every couple of seconds.

I have the same in logs for my 4 ESX 4.1u1 hosts, no idea what is the cause and how to resolve this. I didn't find anything valuable in the net, what would help me to get rid of these error messages.

I'm getting the same thing - it seems to happen every 20 seconds. Fills up my logs - very annoying to find real errors!

I'm also running 4.1 ESXi... no clue as to what this means and I 'm assuming its erroneous as my server has been up almost 8 months with no noticable problems.

Hello,

thanks for pointing to the another thread. If I understood it well, there is said the messages won't appear if ISO images are not mounted. As far as this was not resolved by VMWare for nearly two years, should I wrote some script to periodically unmount all virtual CDs from my machines ? We have more than one administrator, so the script could be sort of supervision on them, but I am not sure there is an API call for testing the ISO was not actively used recently. Or does it mean the error message is actually a harmless garbage, which should be ignored ?

Thanks.

hi!

i consider this message as harmless - it disappeared when "Client Device" was selected.

its hard to say if an automated unmount is a good idea, it depends on your customers and environment .)

this script might contain some useful parts for you: http://www.virtu-al.net/vcheck-pluginsheaders/vcheck/

Thank you very much, it´s great to hear there is no real problem and we can these log messages ignore. Thnaks also to pinting to the complex scripts.
