AW: [mapguide-users] MGOS 2.0.1 Crash Issues

Wed Aug 20 12:44:08 EDT 2008

Hallo,

is there in the mean time soume kind of solution / workaround for these
problems ?

I continue to have server crashes whith raster files and I too suggest that
this is really a threading problem in MG / GDAL Provider;

And because those with instability problems all seem to have IIS / .NET are
there any suggestions to modify IIS parameters and / or the serverconfig.ini
?

Kind regards, Hans

Have you tried to add the provider(s) as having a connectionpoolsize of one?
(in serverconfig.ini)

It is bound to give really bad performance, but it may give stability.
If it gets stable with only one connection, the issue is likely a threadding
problem in MG or the provider. 

Regards, Kenneth Skovhede, GEOGRAF A/S

Something else I forgot to mention, thanks for bringing that up Andy! 
I'm running IIS / PHP and using MySQL for the backend (using odbc
connections instead of mysql connections)

I have similar crashing problems with 2.0.1 and also suspect raster
issues,
although there are no clues in the error or event logs about this.  The
reason I suspect raster issues is that when things start to go wonky, maps
with no raster work for a little while maps with raster fail to render.
Eventually, mgserver faults and locks up.

The one common denominator for those with instability issues seems to be
running MGOS with IIS / .NET.  Is that the case for all with these
problems?

how do they perform if you remove the rasters ?

The old server is no longer in use so I can't give specifics on its
specs.
The new box is:

Windows 2003 Server Standard Edition SP2
2x Intel Xeon CPU E5410 (Quad Core) 2.33GHz
IIS6 - Worker Isolation Mode (8 Worker Process Web Garden for MGOS
Application Pool)
4GB RAM

Attached is my serverconfig.ini file. I didn't make many changes to it,
other than changing the repository paths. I honestly am not 100% sure of
what effects most of the settings have on the system.

Here's a list of the currently available urls in case someone might can

see

something I've done in the maps that could cause some of my problems:

http://www.tscmaps.com/mapguide/mapviewer/?state=ms
<http://www.tscmaps.com/mapguide/mapviewer/?state=ms&county=forrest>
&county=forrest
http://www.tscmaps.com/mapguide/mapviewer/?state=ms
<http://www.tscmaps.com/mapguide/mapviewer/?state=ms&county=lafayette>
&county=lafayette
http://www.tscmaps.com/mapguide/mapviewer/?state=ms
<http://www.tscmaps.com/mapguide/mapviewer/?state=ms&county=lee> &county=lee
http://www.tscmaps.com/mapguide/mapviewer/?state=ms
<http://www.tscmaps.com/mapguide/mapviewer/?state=ms&county=lowndes>
&county=lowndes
http://www.tscmaps.com/mapguide/mapviewer/?state=ms
<http://www.tscmaps.com/mapguide/mapviewer/?state=ms&county=oktibbeha>
&county=oktibbeha
http://www.tscmaps.com/mapguide/mapviewer/?state=ms
<http://www.tscmaps.com/mapguide/mapviewer/?state=ms&county=sunflower>
&county=sunflower
http://www.tscmaps.com/mapguide/mapviewer/?state=ms
<http://www.tscmaps.com/mapguide/mapviewer/?state=ms&county=tunica>
&county=tunica
http://www.tscmaps.com/mapguide/mapviewer/?state=ms
<http://www.tscmaps.com/mapguide/mapviewer/?state=ms&county=winston>
&county=winston

They all use the same layer styles...I just copy the layers to a new

county

folder, change where the file points to and add it to a new county map.

Each

county has a set of ECW raster files.

can you describe the specs of the two machines ?

had you tweaked the serverconfig.ini for the size of the machine?

yeah, I had that in place. It's odd that some of these errors only
started
happening on this new box which has a lot more horsepower than the
previous
one.

i'm going to keep mgos installed and try to do some testing to try to
figure
out what exactly is causing things to die on me.

That is to bad. It might have been something easy to fix. Was you
installation patched to fix the Firefox 3 crash bug?

Sadly, due to the constant crashes I am having to revert all of our
maps
back
to mapguide 6.3

hopefully things will smooth out more in future releases.
