[jboss-jira] [JBoss JIRA] Commented: (JGRP-637) Reincarnation reloaded: prevent port number reuse through persistence

Reincarnation reloaded: prevent port number reuse through persistence --------------------------------------------------------------------- Key: JGRP-637 URL: http://jira.jboss.com/jira/browse/JGRP-637 Project: JGroups Issue Type: Feature Request Reporter: Bela Ban Assigned To: Bela Ban Fix For: 2.7, 2.6.1 If bind_port (UDP) or start_port (TCP) is used, restarted members might reuse the same port, therefore one could run into reincarnation issues. Solution: if enabled, we maintain a file in the temp dir (shared by all instances on the same host), into which we write ports chosen. When a new socket is created, we read the file, weed out expired ports and pick the next port. Then we write that back to the file and close the file again.
