[mapserver-users] Very strange problem doing a query and hanging on MS 6.4.1

Ok, I think I have found a work around to my issue, now I just have to
update lots and lots of classes in lots of mapfiles and a dozen or so
ajax handlers to update to work around the issue.
I updated https://github.com/mapserver/mapserver/issues/5120
It looks like I can add PROCESSING "RASTER_QUERY_MAX_RESULT=1" to all my
query layers and update the ajax handlers that are making the query
requests. The pain with the ajax handlers is that each one needs to know
what the NoData response is going to be for the specific raster that it
is querying because now mapserver is return the NoData value rather then
responding consistently that "msQueryByPoint(): Search returned no
results. No matching record(s) found."
