>             Project: logback-classic
>          Issue Type: Bug
>          Components: appender
>    Affects Versions: 0.9.13, 0.9.14, 0.9.15, 0.9.16, 0.917, 0.9.18, 0.9.19
>         Environment: At least Debian Etch with JDK5
>            Reporter: Ingo Siebert
>            Assignee: Logback dev list
>            Priority: Critical
>
> I have 5 applications servers and each one logs to one separate SysLog-Server. After Server-Restart, all is working fine.
> But after several days and weeks, more and more servers  doesn't log to he SysLog-Server anymore. But I can't see an Syslog-Error in my Logs.
> I think this bug is related to http://jira.qos.ch/browse/LBCLASSIC-57.
> In my opinion, the most important fix would be to re-creae the SysLog-Appender if an exception/error occurs or to avaid that the SysLog-Appender dies.  
> If I miss one single entry, than that's not nice. But if I miss all entries it's very serve. 
> The SysLog-Appender is useless for me until this bug is fixed.
