Re: [thredds] log4j ThreadLocal noise in logs

i guess we will wait for 1.2.17 and get that in. have you seen when that happens? i see a message about the "log4j 1.2.17 release" from june 2010 (!)

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.
