[mapguide-users] Re: FDO OGR provider stops working with many layers

[Hans Milling]

I finally had some time to test this.

I have now tested on AIMS2012 and MGOS2.2. Both fail after about 100 to 180
layers in a map. It seems like some buffer/file handle problem since it
always fails at the same layer but if you delete a few layers from the map,
it fails at another layer.
MapInfo and OGRInfo tool reports no problem with the .tab/.id/.ind/.map
files. Also using Maestro I have opened each individual layer and previewed
them with no problems.

MGOS2.2 and AIMS2012 then reports "FDO Exception. Connect failed":

I can still connect to Maestro but the OGR provider does not work at all
until restart of the MGOS2.2 server.

In AIMS2012 I see something interesting in the log file, it looks like a
file cannot be opened by the service (even though the file is there).
Perhaps some maximum open files limit is reached or something. See error
below. Also the service therefor does not work at all, after this (need to
restart the service).

Any other suggestions would be nice!
