Hi all I am experiencing severe memory issues running Geoserver in a Kubernetes container.
Running a simple JMeter test with a static GetMap request (point layer in PostGIS) with 30 concurrent requests, Geoserver memory usage steadily increases until it reaches the JVM limit and causes an out of heap memory error. I have tried various different GC and other JVM options but all behave in the same way. GC does seem to be operating as I can see the memory usage regularly going down, but not as quickly as it goes up. I am running Geoserver 2.15.2 with Oracle Corporation: 1.8.0_242 (OpenJDK 64-Bit Server VM) and Tomcat 9.0.20. The same Geoserver deployment within a local Vagrant VM runs the same JMeter test and remains stable, with memory usage not increasing over time. I'd be very grateful for any suggestions.
