blobcall stub error 1783 post v8 upgrade

Hi All,

Ive been searching most everywhere for a solution to this and created an incident for it which lead nowhere other than some level 1 tech saying it was basically all windows rpc service fault (which was probably in her manuscript, but still completely unhelpful).

Anyway, my problem was this when using application aware backups after we upgraded from v7 to v8:
Code: Select all
12/2/2014 5:37:27 PM :: VSSControl: FinishSnapshot failed
Failed to execute VIX command: [RPC function call failed. Function name: [BlobCall].
RPC error:The stub received bad data.
 Code: 1783].

When application aware backup was turned off, these machines got backed up just fine.

The usual suspects, restarting vmware tools, checking whether logins where actually assigned after the upgrade, double/triple checking logins, making sure vmware tools where all up to date, rebooting VMs etc etc.. all of them made absolutely no difference.

What did in the end work was deleting the VeeamVssSupport service (sc delete VeeamVssSupport from a prompt with priviledges).

After that everything worked as expected (i didn't need to reboot the VMs after this change).

We had this happen on 5 or 6 machines post the upgrade, some exchange, some mssql and one AD server, so there doesn't appear to be a clear pattern.

So heres to hoping this gets picked up by a google bot so you don't have to waste your time finding a solution.

Regards,
Steffen

I've actually had that error message myself on a couple of VM's. Thanks for the post! Hopefully Veeam will identify and fix this before I begin rolling out V8 everywhere.

Thanks,
Patrick

Hi Stefen,

But are you still able to take an application aware backup after deleting the VSS service from Veeam?

Thanks for the confirmation,

Kurt

Yes, it is a run-time process, will be re-deployed on the next job run.

Solution works fine, but without a reboot of the affected VM after deleting the service it didn't work for me on the first retry of the job.
Veeam recreated the service, managed to start the service, but its startup type was set to disabled (strange effect, because a disabled service usually cannot be started).
Trying to delete the service again yielded an error 1072, only after rebooting the VM the service disappeared and the job retry succeeded.

I confirm: with Windows 2008 R2 I had to reboot the machine to have the VeeamVssSupport service gone.
Afterwards the backup was OK.

I can confirm that this also fixed the same error on a 2008 R2 terminalserver. I did not have to reboot the computer.

It might be worth opening a ticket to find out the root cause of stalled Veeam VSS service. Thanks.
