We have been having a lot of server issues today where I have had to reboot the server every hour or so.
I have seen there is a lot of reports of scaling issues with the federation that they say may cause issues.
To test if this is the problem we are experiencing, I have turned federation off for a few hours, maybe overnight.
I will let you know as soon as I know more.
In the meantime, I apologize for the inconvenience.

It was configured to a much larger machine. So I plugged in the specs for my linode and updated it.
I also upgraded to V17.4 even though that breaks images for some reason.
I figured better to be up and running smoothly with no images, then up and down all the time.
I will watch the server today and see if it performs better and let you know.
Fingers crossed.
Good news, these tweaks have fixed the cpu spikes and the Disk i/o spikes.
You should be seeing better performance.
Still researching what is causing the images not to display.
