Description Frederic BORRY 2007-01-08 04:17:19 UTC

When shutting down an application using a RollingFileAppender in tomcat we have :
log4j:ERROR Error occured while converting date.

Comment 1 Chris Halstead 2007-01-23 11:33:49 UTC

Is it possible for you to provide a simple test case that produces this error? 
Does the issue only occur when shutting down a clustered app?

Comment 2 Frederic BORRY 2007-01-24 00:43:16 UTC

It's hard to write a test case to produce this error... 
All I can tell you is that this happens on a 2 node cluster, when redeploying an
application.
I assume the application class-loader (log4j jar is in WEB-INF/lib) has already
made some clean-up while the replication thread starts a session replication
that involves logging.

Comment 3 Chris Halstead 2007-01-24 11:26:40 UTC

Does the issue occur if you move log4j.jar up to a non-webapp-specific
classloader location, e.g. $CATALINA_HOME/common/lib?

Comment 4 Frederic BORRY 2007-01-25 05:19:06 UTC

I'm afraid I can't perform that test : the application is running in a
production environment along with other appliaction. I can't afford to risk to
reduce the stability of the system.
Maybe I should post this bug in the Tomcat product ?

Comment 5 David Sperling 2007-01-28 07:34:14 UTC

I get the same error message in Eclipse when I use the manager webapp
that comes with tomcat 5 to reload a webapp. I've got the 
log4j-1.2.8.jar jar in WEB-INF/lib/ and common/lib/

I'm running Apache Tomcat/5.5.16

Comment 6 Chris Halstead 2007-01-31 09:40:38 UTC

Take a look at ASF BZ 39699: http://issues.apache.org/bugzilla/show_bug.cgi?id=39699

I think that this is the same as your issue, and it was fixed in Tomcat >5.5.17.

Comment 7 Eric Bloch 2007-04-23 11:10:28 UTC

I'm seeing a similar bug during an app reload.  log4j-1.2.8 and commons-logging
(1.1) in WEB-INF/lib.  If I move them to common/lib and plop down a
log4j.properties the bug goes away but this blows my log configuration
(WEB-INF/classes/log4j.properties) for my app out of the water

I have just come across this issue in TC 6. Log4J ist in webbapp's /WEB-INF/lib.
no default log4j.properties but customized Log4j settings controlled by webapp

In TC 5.0 in the same setup this did not occur.

Marking as WORKSFORME as I think this is the Tomcat class reload issue.  Refile a new bug report, if there is new information.
