Yes, please let me know, thanks. My ticket has been open with level 3 for a week with no response so hopefully between the two of us we can get an answer.

For those who is still experience BSOD after installing patch #3, we have confirmed that the issue is caused by 3rd party antivirus products affecting our change tracking logic. We were finally able to reproduce the issue in our own lab by installing McAfee. We also saw the same issue caused by another antivirus in the customer's environment.

We are looking at ways to work around this.

Just to add that I'm seeing BSOD issues on my hosts with patch 3 installed and Sophos AV running. With all Sophos services disabled on my hosts, Veeam backups complete successfully.

Any news on how Veeam are progressing with this issue?

Checked, and looks like the patch is still being tested internally, and piloted with a single customer who uses McAfee.

I've asked to provide you with the pilot fix as well. However, we cannot be sure if it will help with your antivirus. If it does not, please send us the crashdump.

We've seen different antiviruses affecting system behavior differently. Many of them are literally "braking" some OS functionality to make the life harder for viruses, however this obviously affects "normal" low-level applications like our change tracking as well. Best bet with any antivirus is to exclude CSV volumes from real-time antivirus protection, but unfortunately this may not disable that obfuscation functionality that causes us problems.

I'm not sure if I'm that person, however Veeam has installed the patch on my Dev environment (with Mcafee) and so far it has been working great. Hoping this fixes it.
