We are running a rails 2.3.5 app with Jruby 1.4.0 on Tomcat 6.0.29.
I notice when we shutdown Tomcat we get a bunch of messages like
following in catalina.out:
Nov 15, 2010 1:00:11 PM org.apache.catalina.loader.WebappClassLoader
clearReferencesThreads
SEVERE: The web application [/myapp] appears to have started a thread
named [Timer-0] but has failed to stop it. This is very likely to create
a memory leak.
Anything to be concerned about? Are these timers actually being used by
the rails app?
