Hello,
Thanks for responding so quickly. Though it's not included in the copy of
my log4j.properties file I pasted into the beginning of this email thread, I
did set the port with this line:
log4j.appender.telnet.port=23
It made no difference. Actually, the problem appears to be that, when
Tomcat reloads the web application after I run a build, TelnetAppender
throws a BindException, with the message that the "Address [is] already in
use". Perhaps TelnetAppender is failing to dispose of its socket connection
properly. If I shutdown and restart Tomcat, TelnetAppender works fine until
the next time I reload the webapp, even without explicitly setting the port.
If you like, I'll log a bug for this.
Cheers,
David
P.S. Here's the stacktrace

Howdy,
Did you do as the bug report suggests and set the port explicitly even
though the docs say that's not required?
