Cycling a channel results in leftover timer threads --------------------------------------------------- Key: JGRP-1971 URL: https://issues.jboss.org/browse/JGRP-1971 Project: JGroups Issue Type: Bug Reporter: Bela Ban Assignee: Bela Ban Fix For: 3.6.7 When a channel is cycled a few times in the same process (creating a channel and calling {{destroy()}} on it, there are leftover timer thread. The reason is that the timer thread pool uses {{LazyThreadFactory}}, which keeps a list of threads to potentially rename them at runtime. The element are weak references to threads, but because we don't run out of memory, those refs are never garbage-collected. SOLUTION: add a method {{destroy()}} to {{ThreadFactory}}, and {{LazyThreadFactory}} would simply clear the list when called.
