To keep session data, you will have to keep a copy of the open sessions
during restart.
I have not tried to do this, but you might be able to make a file copy
of the "Session" folder and files before the restart,
and copy it back in after.
If the server stops responding, you will not be able to query it for
open sessions, so I think the above approach is pretty much the only way.

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,

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,
