Hi Jiri,

I have a similar difficulty. I'm trying to disable the stack trace output in my SyslogAppender, but the documented methods don't seem to work. I suspect our problems are related.
I'm sure we're not alone in this. Search back in the archives, and you'll find at least one other person with a related problem.
If you get your problem fixed, please post back to the list. I'm still struggling.

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 Jiri Sitina wrote:

Hi, we have recently switched from Log4J to Logback. Logging seems to work well except stack traces in SyslogAppender. They are prefixed just like remaining log messages. Is there any way how to disable this prefix and ensure they will be printed in the same manner like with Log4J SyslogAppender?
