Description

After failing to send a message to syslog-ng using tcp, the connection is reported as closed in syslog-ng, yet seems like appender is unaware. Even with ignoreExceptions='true', logger still happilty sends messages through, none of which actually hit the server.

 

Used bababit/syslog-ng docker image for server:

 docker run -it --rm -p 7514:514/udp -p 7601:601/tcp  balabit/syslog-ng -evd

 

...and some groovy test specification cobbled-together to test (FWIW, as a sanity check, it is able to send via udp)
