During this time, the VM did not respond to commands and could not be pinged. When the hotadd completed about 30-40 seconds later, the VM would start responding again, but the replication job (as well as any other jobs running on that proxy) would fail with timeout errors. Only the destination proxy seemed to lock up, the source proxy never did.
My workaround: Once I figured out the issue, I configured one proxy to only use NBD mode and assigned that proxy as the destination proxy for my replication jobs. Since I did this, I have not seen the issue again.
My question is, has anybody else seen this? If so, is it an issue with vSphere, or with Veeam? I am running vSphere 5. Any input would be appreciated as I'd like to be able to use hotadd for writes. I didn't want to bother Support with this yet since I have a good workaround.

Switching to NDB solved this for me.
skoch wrote:Add me to the list of people having the issue. I have also opened a ticket with Veeam. What is everyone using for storage for their destination proxy (Fiber, iSCSI, onboard)?
Windows 2008 R2 for source and target proxy.
Target vSphere storage is all iSCSI
