[MapProxy] MultiApp and Multiple MapProxy Servers

[Keith Moss]

Hi all,
 
We've been running into an occasional spot of bother running MapProxy on multiple servers.
 
We have four servers running MapProxy in the 'serve-multiapp-develop' mode pointing at the same directory of config files. Our frontend is an OpenLayers map that has each of the four servers as a source of WMS tiles - in effect this means that of the, say, 28 tiles that make up each map each server is getting a request for 7 of them.
 
We're noticing that when there is a new config file for a layer that hasn't been accessed yet one of the four servers will almost always respond with the error I've attached. There's no particular pattern to it that we've observed.
 
Has anyone spotted an error like this before?
 
Cheers,
 
Keith
