Subject Re: JCS Hangs on server shutdown.
Date Fri, 05 Dec 2008 08:13:46 GMT
Hi Scott,

I have not seen anything like that. What OS are you using? Maybe try an
older version of Java.

There are some changes to the shutdown in the latest (still unreleased
versions). Try one of these:

http://svn.apache.org/viewvc/jakarta/jcs/trunk/tempbuild/

Al
