Zones not triggering

[marvel]

Running ZM 1.27 on CentOS 6.5. Have four cameras setup as "monitor" and all are working fine. Now, it's time to get some actual event recording going.

So I set one cam to Modect. Edited the existing "All" zone, Type is "Active", and I've tried presets of "Fast, High Sensitivity" and "Best, High Sensitivity." The word "Modect" and the source IP show up green in the ZM console (other cams on "Monitor" are orange). Unfortunately, it doesn't seem to be working. I can jump around in front of the cam, wave my hands and such, but I don't see any events.

These errors were found in my log:

zmdc[31136]: WAR [Can't find process with command of 'zmtrack.pl -m 2']
zms[31297]: INF [Got signal 15 (Terminated), exiting]

Not sure if they're relevant or not. Anyway, I could use some help. Thank you!
