[logback-user] Tomcat hanging when logging in an app at the "error" level?

[Michael Andrews]

I thought I would throw this out to the list before I started deep diving. I'm logging with org.slf4j.Logger and logback classic in an app running in Tomcat. Tomcat is using its regular JULI logging. 

When I use:

logger.error(msg);

Everything works great. But when I add a Throwable in there:

logger.error(msg, t);

The connection thread hangs in tomcat. 

Just thought I'd see if anyone has run into this before.
