ThreadGroup should not ever hold on to dead threads in its list
---------------------------------------------------------------
Key: JRUBY-2721
URL: http://jira.codehaus.org/browse/JRUBY-2721
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Affects Versions: JRuby 1.1.2
Reporter: Charles Oliver Nutter
Assignee: Charles Oliver Nutter
Fix For: JRuby 1.1.3
The following code produces a ThreadGroup with thousands of dead threads, which
is part of the cause of Mongrel eventually filling up with dead threads and
refusing connections:
{noformat}
tg = ThreadGroup.new; 10000.times { t = Thread.new { }; Thread.pass; tg.add(t)
}; p tg.list
{noformat}
ThreadGroup should never list dead threads, though it does not appear it should
do anything to prevent a call to add. Needs specs and fix for 1.1.3. Probably
related to JRUBY-2712.
