Same issue here. I see that everytime the Server starts up, though Image Library appears to be working.

same issue here on startup?

Asset Warmup (1/12414)

same.

Maybe this is the reason images are failing to load onto signs after restarts?  This is only happening on restart - once.  Linux btw. Please help

this is most likely from a plugin that is not checking that imagelibrary is loaded, before requesting images (eg. the plugin loads on startup before imagelibrary loads)

i already fixed this problem
