The normal sensitivity should be Medium. High and Very High are usually reserved for machines that you highly suspect are infected. However, I have to admit that I'm stumped why they would be correlated. I found this article and this one and this one from our knowledge base. If it were me, I'd do the following:
1. Uninstall VSE.
2. Reinstall VSE 8.8 patch 2.
4. Try again.
My thinking is that you might not actually be running patch 2. Or that you think you are but something might not be working right.
Either way. Call support back and ask for escalation.
Thank your for information. Well, i was thinking about known bug event 560, but in this case is different. The known bug event 560 was every "X" minutes continuously and with patch 2 I could see that was solved.
I tried reinstall VSE 8.8 patch 2 with same result.
I will try with sensitivity Medium...
