Hello, We are running into a strange problem with Direct Memory buffers. From what I know, we are not using any direct memory buffers inside our code. This is pretty trivial streaming application just doing some dedupliction and union some kafka streams. /Jakob 2015-10-19 13:27:59,064 INFO

JVM core dump running Flink streaming

2015-09-28 Thread Jakob Ericsson
Hi, I'm testing Flink streaming but seems to have some problems with jvm core dumps. I haven't really looked at the heap dump yet. It seems to be related to the G1 GC. If I want to go back to CMS-GC, do you have any preferred settings? # # A fatal error has been detected by the Java Runtime
