[mapguide-users] Out of Memory error problem

[Zac Spitzer]

one option you could try is tweaking the settings under
FeatureServiceProperties in ServerConfig.ini
with shorter timeouts for the connections

can you file a bug for the Shape16 vs Shape31 issue in trac?

what type of feature sources are you using? What size of area are your
maps and at what scale?

Due to the nature of mapping data it is hard to provide test cases for
developers to debug, the holy grail is being able
to provide a mgp file which exhibits a specific issue.

That said, I have a test case uploaded against the samples which falls
over under load with the sample data on windows

overall, stability is rather problematic at the moment with mg 2.0,
some of the demo sites are down at times

http://demo01.dmsolutions.ca/mapguide/fusion/templates/mapguide/slate/ (busted)
http://data.mapguide.com/mapguide/phpviewersample/ajaxtiledviewersample.php
(works, might be mge tho)
http://mapguidebeta.osgeo.org/mapguide/fusion/templates/mapguide/slate/index.html
(working)
