High IO & Tons of errors in log

[Tuxxin]

I finally got around to configuring my POE system using ZoneMinder. I currently have 14 POE cameras online with zoneminder running at 1920x1080 32bit color @ 5FPS. The problem I'm running into is I'm getting about 70+ log entries every second in ZoneMinder (see below), montage is not loading more than 5-6 cameras and the ones that do, are snowy (almost like the pepper static from old tv's). When I view a monitor directly, it looks perfectly fine and works without problem. The system is jumping between 30% and 60% iowait (Using a WD Purple 4Tb).

I am new to Zoneminder and camera systems in general so I don't know all these little tricks/tweaks to get things working properly.

Anyone have any suggestions on what I could try?

Much appreciated!

Start by lowering the resolution by half. Better yet by 1/4.

Use tmpfs for PATH_SWAP. (/dev/shm if Ubuntu 16.x) And make sure you have some free space in tmpfs!

If you are using Firefox look up the montage fix in the WIKI.

What your log shows is exactly why we tell everyone to always use the ffmpeg source type.

Our latest documentation has been updated to reflect that:
http://zoneminder.readthedocs.io/en/lat ... source-tab

The remote source type is no longer being maintained because it attempts to re-invent what ffmpeg & libvlc already do much better.

You nailed it. I updated all of the cameras to FFMPEG and the usage is like night and day. I'm still getting some bugs in the images, but it mostly seems to be coming from the montage. I will just probably use a different browser for viewing in the future. I appreciate your help.
