Re: [mapguide-users] Unhandled exceptions in IIS web tier
Thanks for the responses. James, I also get the same error messages as the one you described. I think they may be related as I managed to create some of them by accident when attempting to catch and work with some of those unhandled exceptions within the mainframe.aspx. They are preceded by another error that looks like: “Faulting application name: w3wp.exe, version: 7.5.7601.17514, time stamp: 0x4ce7afa2….” I just noticed the following post in the Autodesk support site. It looks like this or a very similar issue is considered to be a known issue and will hopefully get patched up soon. http://knowledge.autodesk.com/support/infrastructure-map-server/troubleshooting/caas/sfdcarticles/sfdcarticles/Mapserver2014AppPool-Error.html From: northtron [via OSGeo.org] [mailto:ml-node+s1560n5139435...@n6.nabble.com] Sent: Friday, May 09, 2014 6:55 AM To: Galambos, John Subject: Re: Unhandled exceptions in IIS web tier I think I recall having to set my recycle limits on the AppPool for stability from errors in Mapguide as well.

Several times a day we get logs like A process serving application pool 'MapGuide25AppPool' suffered a fatal communication error with the World Wide Web Publishing Service. The process id was '17544'. The data field contains the error number. with the source being W3SVC. W3svc.exe is the process related to the application pool in IIS that represents the website that holds mapguide. It's tricky for me to figure out what the cause of the errors are. It could be a memory leak in my own application (fairly likely,) so I can't blame mapguide for it off the bat. Basically, whenever my application pool fails, maps stop loading until I manually recycle the application pool. Without knowing the exact cause, the only workaround I've come up with is to configure my application pool to automatically recycle whenever it accumulates a certain amount of virtual memory. I've got it set to recycle at 800 megabytes, but I might decrease that number if problems persist. The hope is that frequent recycling will prevent errors. It's also important to note that my application does not use InProc session handling in web.config. That's the default setting and application pool recycling would reset any sessions (very bad.) Instead I use the StateServer setting. That way session aren't reset upon application pool resets. ___ mapguide-users mailing list [hidden email]/user/SendEmail.jtp?type=nodenode=5139435i=1 http://lists.osgeo.org/mailman/listinfo/mapguide-users ___ mapguide-users mailing list [hidden email]/user/SendEmail.jtp?type=nodenode=5139435i=2 http://lists.osgeo.org/mailman/listinfo/mapguide-users If you reply to this email, your message will be added to the discussion below: http://osgeo-org.1560.x6.nabble.com/Unhandled-exceptions-in-IIS-web-tier-tp5139328p5139435.html To unsubscribe from Unhandled exceptions in IIS web tier, click herehttp://osgeo-org.1560.x6.nabble.com/template/NamlServlet.jtp?macro=unsubscribe_by_codenode=5139328code=am9obi5nYWxhbWJvc0B2YW5jb3V2ZXIuY2F8NTEzOTMyOHw4Nzc1NzM0MDA=.

[mapguide-users] Unhandled exceptions in IIS web tier
Is anyone else seeing unhandled web tier exceptions in a Windows install? We are running AIMS 2014 on Windows 2008 and since mid-April, we are seeing unhandled errors fairly frequently in the Event Viewer. I think this may not be an AIMS specific issue. Here is an example event viewer message: -- Event code: 3005 Event message: An unhandled exception has occurred.

Re: [mapguide-users] Limiting number of results from Maestro QueryFeatureSource or mapagent SELECTFEATURES?
Fantastic--thanks Jackie! Is it possible to somehow push this limit all the way through to the server side? Perhaps I'd better explain what I'm trying to do. We have a rather large map (500+) layers and are trying to tune it to improve performance. As part of this, I've written a script (using the Maestro API) that reads the map definition, and then isolates layers one at a time in a runtime map, and records the amount of time it takes to render random locations on this layer at the display scales defined for the layer. To make sure we're rendering locations that actually display features for the layer, I query 15-20 features from the layer in advance, and then zoom to the location of the centroid of each feature. I am doing this via the QueryFeatureSource API. I believe that because the limit doesn't get pushed to the server, in effect I am querying all of the features for each layer in the map, and they're all coming across the wire in XML where currently the script only ends up deserializing as many as the limit. It is working right now, but it would be nice if it was a little more efficient. I'm wondering if there is a way to avoid bringing all the features across without having to get into feature class specific filters etc. -- View this message in context: http://osgeo-org.1560.x6.nabble.com/Limiting-number-of-results-from-Maestro-QueryFeatureSource-or-mapagent-SELECTFEATURES-tp5135715p5136552.html Sent from the MapGuide Users mailing list archive at Nabble.com. ___ mapguide-users mailing list mapguide-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapguide-users
