[logback-user] SyslogAppender stacktrace logging prefix

[Jiri Sitina]

Hi, 
I was wondering how to avoid #011 and #012s in syslog output but still with
no noticeable result. 

Don't you have any ideas what might make syslog accept tab and new line as
it does with log4j?


Thanks in advance,

Jiri Sitina
