Hi !
We get an uncaught exception from Log4J which causes our application to
crash.
More specifically, we are using Log4J 1.2.13 with a JDBC appender which
relies on the MySQL Connector 3.1.13 and when the application invoke the
Logger.debug() method the following exception is not caught by the Log4J
framework.
This exception is throwed by the connector because the MySQL server is
unreachable.

We would like our application to simply ignore this appender in such case.
Is there a way to do this without changing our application code base ?
Is there any Log4J configuration parameter which could enable Log4J
appender exception handling ?
Thanks a lot for your help !
Best regards,
