Hello Igniters / Val, Since last few weeks, we are seeing out of memory issues on ignite servers, today I was able to capture the heapdumps and that is pointing to following classes -
Our version of Ignite is 1.7.0. 15 instances of "org.apache.ignite.internal.processors.affinity.GridAffinityAssignmentCache", loaded by "sun.misc.Launcher$AppClassLoader @ 0xc0029998" occupy 453,929,512 (76.41%) bytes.
