We'd like to propose including this fix into 1.9.0 as well: https://github.com/apache/geode/pull/3362 https://jira.apache.org/jira/browse/GEODE-6544
This fixes a memory leak caused by a thread leak in Pulse. Every time a user signs out, a thread is left running. The fix for GEODE-6544 stops that thread when the user signs out. - Aaron and Kirk
