[jboss-jira] [JBoss JIRA] Resolved: (JGRP-878) FD_SOCK: client connection handlers are not removed from list

FD_SOCK: client connection handlers are not removed from list ------------------------------------------------------------- Key: JGRP-878 URL: https://jira.jboss.org/jira/browse/JGRP-878 Project: JGroups Issue Type: Bug Reporter: Bela Ban Assignee: Bela Ban Fix For: 2.6.8, 2.7 [Igor Postelnik] I'm working on a system that uses JGroups 2.6.3 to maintain cache coherency. The system has a mix of long-lived services and short-lived jobs, both of which join the group. We have noticed OOM errors in our long-lived services and profiler shows FD_SOCK is the culprit. The elements of FD_SOCK.ServerSocketHandler.clients are never removed, even when ClientConnectionHandler terminates. It looks like ClientConnectionHandler should just hold a reference to the ServerSocketHandler.clients so that call to remove in the finally block of run() method modifies the original list. Instead, ClientConnectionHandler makes a copy of the list and so the original list held by ServerSocketHandler.is never updated.
