We have 9 or so Linux based Unified Connection platforms that Orion is seeing the volumes disappear on. The Windows based platforms do not. I don't think it is entirely Linux itself, I have a few other Linux(Fedora) servers that don't have volume issues. I also noticed that not all the callmanagers are reporting phones and gateways, and again it is the Linux servers that are doing this. I am using SNMP V3 to communicate with them. When I had the server here in the office I didnt see this problem, but now that it is deployed in our Colo and going across the WAN I am seeing it. This server is in one Colo, the rest of the servers are in our other Colo. The previous connection when it was in the office was through our backbone from one Colo to the other over a pair of DS3's, the new colo routes over a GRE tunnel for now until we get the Fiber connected. Any ideas why I am seeing this?
