[logback-user] logback prints stack trace twice when writing to syslog

[kumar k]

Hello,

I am writing my dropwizard logs to syslog using logback pattern. I see an
issue for stack traces prinitng it twice(once linearized and once as
multi-line). Is there any parameter which could avoid this issue?

Config:

syslog: enabled: 'true' threshold: ALL host: localhost facility: local6
logFormat: “MMJ: %p [%logger{0} %t] %c{30} %m [%X]%n
%throwable{separator(|)}"

*Logs printing twice:* Multiline: 2020-04-27T13:20:46+00:00 MMJ MMJ: ERROR
