Hello everyone.
I've made a few tests, but unfortunately, it seems that the exclusions don't help so much in terms of performance. I also had my VMs getting stuck at login when mounting several AppStacks (it did this with 3 stacks, not with 2, and I didn't try with more than 3 stacks).
My security colleague re-opened the case at Symantec. Maybe if some of you have a case number to share so we can ask them to link those cases, it might help.
Regards,
Carlos.
