Forticlient blocking chrome.exe because it's BitTorrent

[mike_dp]

I got a weird problem. Once in a while and on some PC not all, Forticlient detect chrome.exe as a P2P app (BitTorrent).

I use EMS as profile controller and I block the P2P App category. I have EMS 1.0.2 and Forticlient 5.4.1 under Windows 7. The rest of the traffic is blocked or authorized like it should.

For some reason after a little while of browsing, the Forticlient detect chrome.exe as BitTorrent. It happens on some PCs (maybe 10 reported) and they don't have any specific BitTorrent extensions. Also, when it happens when they are on-net (connected to our business network) I don't see anything like this in the Fortigate logs so it really is caused by Forticlient (we also block P2P app traffic at the office). They either have to close chrome or reboot their PC to make chrome work again.

I have attached what I got in one Forticlient log. I have activated the debug logs for Forticlients since then and I'm waiting for it to happen again.

Any ideas?
