Any known issues between P0werPath and Symantec Norton AntiVirus?

I recently installed NAV, and suddenly during the week at 7:50 PM, power path loses its connection to CX 600. NAV is only new app. installed. Only other thing was a scheduled power outage where I work. CX 600, brocade switches and all hosts had to be powered down. Not working right since power outage. However, it's only affecting 1 host (I have 8 hosts connected to brocades). Brocades show no errors or "events" for that time, and seeing it's only one host and not all my hosts I feel its not a brocade issue. Could be replication manager snaps as well. They run Mon-Fri, and this is when PowerPath loses its connection. Over weekend, with no snaps running in Replication Manager, host server never loses its connection. Tonight in fact, I put snaps on hold and the server was fine. So, problem could be some issue with RM snaps. Not too sure.

i only found this that has any relevance:
