We have a 3 server setup, 1 repeater - 2 edge, running under VMware ESXi on a HP ProLiant DL 120 G6, with 4 Xeon X3430 @ 2.40GHz with 12G of ram and 2 gigabit ethernet (onboard). We only have these 3 machines running there.
repeater 1 -> 2 procs + 2G of ram
edge 1 -> 4 procs + 4G of ram
edge 2 -> 4 procs + 4G of ram
The repeater recieves 4 streams and in turn spits out 8 connections (4 per edge server if I understood correctly the repeater-edge configuration).
We only do live streaming for now, so I guess disk speed is not important.
We’re get around 700-800 connections for the 4 streams (2 are 420k, 2 are 96k).
Everything is running smooth, but we just noticed a weird trend while monitoring the servers.
At a certain point, apparently not related to number of connections, the processors spike to 90%-95% and stay like that.
The machine doesn’t die, and it keeps serving fine. I find it weird that the machine is running at 10%-20% constantly and it suddenly spikes as described before.
Any idea on what can be causing it? It happens on both the repeater and the edge servers.
