16743	HTTP timeout errors in tile cache	anonymous	anonymous	"My network connection is currently poor and I'm getting a large number of timeout errors (stacktrace below). The tile cache behaves erratically - some tiles don't load others, already loaded, randomly disappear. Reloading a tile or all tiles helps but after a while the tiles start disappearing again.

Version 14180.
