If you’re running ESX 5/5.1, do NOT upgrade/install Trend Deep Security 9. There’s a good chance you will find this bug… we sure did!
I found this after 3 of my ESXi hosts intermittently PSOD (failed, died, kicked the can).
It’s always fun for your environment to be the reason that a tech-vendor has to issue a KB article.
The details are at the link above, but here’s the most important fact —
The following customers are affected:
Customers using Deep Security Virtual Appliance (DSVA) 9.0 on ESXi 5.1 or 5.0
Customers running any Deep Security network security feature (Firewall, Intrusion Prevention, Web Reputation)
Customers who are using only Anti-Malware or using DSVA 8.x will not experience this issue.
