Hi all,

I have been seeing this error with log4j in my logs after I shutdown TDS...

SEVERE: The web application [/thredds] created a ThreadLocal with key of
type [org.apache.log4j.helpers.ThreadLocalMap] (value
[org.apache.log4j.helpers.ThreadLocalMap@b890dc]) and a value of type
[java.util.Hashtable] (value [{startTime=1331669953595, ID=8}]) but failed
to remove it when the web application was stopped. This is very likely to
create a memory leak.

I dug around some and found they have a fix for this in log4j rv1231361,
but will be released with 1.2.17.  TDS currently comes with 1.2.15 in
/WEB-INF/lib.  Hope this helps.
