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. https://github.com/pedros007/gdal_mapserver_memory 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: https://github.com/pedros007/gdal_mapserver_memory/blob/master/mapfiles/indonesian_redcross.map#L15-L18 Thanks, Pete _______________________________________________ mapserver-users mailing list [email protected] https://lists.osgeo.org/mailman/listinfo/mapserver-users
