So I switched from Record to Modect and the issue seemingly has gone away. I suspect the system ended up I/O bound when it went unresponsive. Since I do not need full time recording, this solution works for me.

Here is the last top output at 2pm (which is apparently when it went unresponsive). I rebooted it around 10pm. CPU usage looks acceptable. Maybe its I/O bound?

VM went unresponsive again. I added this line:

@bbunge: The memory usage never seems to climb over 2gb. While the rest ends up allocated in cache, it is never reported as used.
Had to restart again. Waiting to get a couple days of data for mysqltuner.

@SteveGilvarry: I will see what I can get out of it net time the load jumps.

TL;DR: Zoneminder processes go out of control after a day or so of running cause huge load (upwards of 100). Where do start looking for the cause of this? Setup: I am running 8 IP cameras at a remote location. The are ZModo ZP-IBH13-W. These cameras are set to broadcast at 720p 4fps due to ...
