Hello! Maybe it's network problems and not full GC. As you can see from logs there's failure to acknowledge a discovery message.
As for "re-discovery" - as far as my understanding goes, that't not how Ignite works. Client nodes will indeed try to re-discover server, but server nodes consider themself "segmented". After that they *could* proceed working solo, but by default they won't. This is governed by segmentation policy in Ignite configuration. And by default it is "stop", i.e., shutdown node. https://ignite.apache.org/releases/latest/javadoc/org/apache/ignite/plugin/segmentation/SegmentationPolicy.html There's a possibility of RESTART_JVM and that's the one you should probably set for the behaviour you desire.
