unable to quiesce an application
i have my backup exec 2010 r3 running for one year without problem. i have my production running in Vsphere 5.0 (vcenter U1 and esx 5.0 U1) still running ok. but when i started my test esx1 5.0 and another esx2 5.0 U2 both build 914586 and i deploy Vcenter 5.0 U2. My backup exec r3 stop running properly with error... "An attempt to take a snapshot of a virtual machine failed because it was unable to quiesce an application."
I have lots of testing... if i put the vm shutoff, backup will work but of course this is not acceptable... and even if i put vm to vcenter 5.0 U1 and esx 5.0 U1, it will now fail too but rest of the prod vm are still fine.
below is just the solution from backup exec,
but i'm using backup exec 2010 r3 now, it's higher than the recommended solution which is upgrade to backup exec 2010 r2.
anybody encounter this kind of problem?
thanks for any comment you may add and more power,
