Project: Geode
Issue Type: Improvement
Reporter: Gregory Chase
I'm evaluating geode for our product. I started with a simple test to check the
behavior of geode on low-mem:
- launch a locator and a single server with initial-heap==max-heap==4GB,
critical-heap-percentage=90%, eviction-heap-percentage=80%
- I see that gfsh passes in addition the following jvm params to server:
-Xms4000m -Xmx4000m -XX:+UseConcMarkSweepGC
-XX:CMSInitiatingOccupancyFraction=60
- create a partitioned region - run client which connects to locator and get
the region as PROXY (i.e. no local cache)
- the client fills the server with elements until it gets
ServerOperationException due to low memory (as expected)
- now, I remove all elements from the region and try run the client again - the
client fails on the first put operation (although server is empty!)
My question is: why doesn't the GC collect removed items (I see on server
status that currentHeapSize=3151MB, maximumHeapSize=3866)?. I'm expecting to be
able to put data in the server if its empty...
Thanks.
