AW: [mapguide-users] 2.0.1 / IIS / .NET instability?

[G.E.O.-Consulting / Hans Mörschell]

Hello,

 

we are using MGOS 2.0.1 / IIS7 / .NET whith an asp solution and the ajax
viewer. We have similar errors when using raster images (GDAL , MrSID and
Tiff mages), I think these problems where already discussed a little time
ago, but as far as I have seen there are no solution yet ???

 

At the moment we use a little monitoring program written in VB to check
every 30 seconds if mgserver is responding using a simple test layout.

 

Unfortunately restart of mgserver results in loss of session data so this is
not a perfect solution. I would be very interested in some other ideas how
to restart mgserver without loosing all user data, are there any suggestions
??

 

Thanks,

Hans Mörschell

Hi All,

I migrated my public demo server to 2.0.1 a few weeks ago.  Since then, I
have found MapGuide to be much more unstable than it had been previously.
The service completely locks up (although appears started to Windows) and
cannot be restarted using normal methods and PSKill is the only solution to
restarting it.   When looking at the server, I usually see an unhandled
exception error dialog with mgserver.exe the faulting module.   The one
thing that is different now is that we’re using a Fusion layout instead of a
standard layout for a site that is regularly accessed.  The Windows event
logs don’t yield many clues, but the MGOS error.log has many of these
entries:

<2008-07-17T00:06:08>   Fusion Viewer   xxx.127.xxx.41  Anonymous

 Error: Invalid argument(s):

        The value cannot be less than or equal to zero.

I know some folks were working on something to determine if the mgserver
service had locked up and, if so, restart it.  Was anybody successful in
making something like this work?  It’s not fun to hit your map site only to
find it not working.

Thanks,
