[mapserver-users] Higher Memory Usage with vsicurl and gdal > 2.2.4

[Peter Schmitt]

Hi,

I run MapServer in a Docker container. I noticed its memory utilization
climbed much higher than expected. This seems to happen only under the
following conditions:

* Files are accessed network-based filesystems (I tried both /vsicurl/ and
/vsis3/)
* Using gdal  > 2.2.4 (tested with 2.3.0, 2.3.2 & 2.4.1.  I see the same
behavior with both MapServer-7.0.7 and MapServer-7.2.2.

I had a hard time isolating this to GDAL and could not reproduce with
similar gdal_translate commands.  So I put together a little example to try
and demonstrate the problem.

Does anyone have any ideas as to what might be going on? I tried various
cache settings, which do not seem to reduce memory utilization:

Thanks,

[mapserver-users] Scaled symbols in Legend

[Basques, Bob (CI-StPaul)]

All,

Beena  while since I set up scaled symbols with MapServer.  Is the dummy layer 
approach still the best way to handle statically sizing the symbols of a scaled 
symbol layer in the legend?

Thanks

bobb

Re: [mapserver-users] Optimize Mapcache to work with both Mapserver and ArcGIS clients

[Yves Jacolin]

About resolutions in MapServer, here what we have in your mapfile, with
some extra comment:

# RESOLUTION and DEFRESOLUTION default to 96. If you
# change RESOLUTION to some other value, also change
# DEFRESOLUTION. See
# http://mapserver.org/development/rfc/ms-rfc-55.html
RESOLUTION 96
DEFRESOLUTION 96
