[Basques, Bob (CI-StPaul)]

All,

A good presentation by myself and Jim K. last month on Potree and how we’re 
using it.  Good conversation too.

Last Meeting recordings posted at chapter link at the bottom of this email.

Upcoming Meeting:

Title: Perry Nacionales – Aerial Mapping with Drones

Description:  I will talk about the basics of photogrammetry and touch upon 
some of the benefits of using unmanned aerial vehicles (drones) in mapping. I 
will then go through some tools that are available for drone mappers, 
highlighting the open source geospatial software. Lastly, I will cover some 
relevant federal and state laws that govern drones and drone mapping.

Here is the connection info:

[mapserver-users] MapCache: Memory leak in WMTSCapabilities request?

[Schmid Andreas]

Hi

I'm running MapCache 1.10.0 in a Docker container. The image is based on 
debian:bullseye; Apache and MapCache is installed into the image with apt. 
Everything works fine; however when I set the health checks to regularly 
request the WMTS Capabilities at mapcache/wmts/1.0.0/WMTSCapabilities.xml, the 
memory usage of the container increases continuously. In a test setup with 12 
of these requests per minute and no other requests, the increase is around 25MB 
per day.
When I set the health checks to simply request a certain tile, there is no such 
increase of memory usage.

Does this mean there is a memory leak in the WMTSCapabilities functionality? 
Something similar has been described in 
http://osgeo-org.1560.x6.nabble.com/Memory-leak-in-mapcache-td5401587.html two 
years ago, but no real solution has been found there.


Best regards,
Andy
