Tomcat-4.0.3 to Tomcat-4.1.18 causes LogConfigurationException

[Daniel Haynes]

Hi,

We've upgraded from Tomcat-4.0.3 to Tomcat-4.1.18 and are now getting an
intermittant error which causes Tomcat to fail completely :(

The error is in stderr.log:

21479094 [Thread-13] INFO filters.TimerFilter  - /euroTrading/action/logout:

We did not get a problem with Tomcat-4.0.3. The application uses
log4j-1.2.6.jar, commons logging contains:

org.apache.commons.logging.Log=org.apache.commons.logging.impl.Log4JCategory
.

Does anyone have any ideas what is causing this ?
