0This error occurs at the end of reading in a very long file, whose last
form says "make the image", which then takes a long time. Just recently
we went above some threshold, beyond which the fileserver gets unhappy.
Without sources handy on-line and no documentation that I can find after
looking, is there some simple timer somewhere that I can change the value
of, to get this to be a bit more patient. Thanks.
