TimeScheduler3 could spawn too many threads ------------------------------------------- Key: JGRP-1663 URL: https://issues.jboss.org/browse/JGRP-1663 Project: JGroups Issue Type: Bug Affects Versions: 3.3.3 Reporter: Igor Mazur Assignee: Bela Ban Priority: Optional Fix For: 3.4 Attachments: global.xml, site.xml With default timer thread pool settings this code could spawn thousands of threads: protected void submitToPool(final Task entry) { try { pool.execute(entry); } catch(RejectedExecutionException rejected) { // only thrown if rejection policy is "abort" Thread thread=timer_thread_factory != null? timer_thread_factory.newThread(entry, "Timer temp thread") : new Thread(entry, "Timer temp thread"); thread.start(); } } On my environment I got 19000 threads.
