>             Project: Log4net
>          Issue Type: Bug
>          Components: Core
>    Affects Versions: 1.2.10
>         Environment: Windows Server 2003
>            Reporter: Kenneth Shih

> Problem: We call log4net from our BizTalk 2006 orchestrations.  We noticed we were missing
logging data. 
>  
> Doing a simple Nunit single threaded test, we would get all logged data. (repeatable)
> In a Nunit multithreaded test, we would notice missed logged data. (repeatable)
> Also, we also noticed  when BizTalk Host, when we lowered the amount of active threads
down to 2 (the lowest we could go) 
>  
> So, We enabled debug tracing in log4net.  We also added various system.diag eventlogwrites
around different parts of our code,  from where log4net was called, and also inside our appenders.
>  
> We noticed was saw an error in the debug tracing (using debugviewer)  log4net:ERROR [EventLogAppender]
Attempted to append to closed appender named [EventLogAppender]. 
>  
> Also, by counting the number of eventlog entries we had from the various points, log4net
itself was not calling the appenders each time it was called to log a message.
>  
> We seen this issue of log4net not calling the appenders, with a variety of different
appenders, like the out of the box file and eventlog appenders and also our own msmq appender.
>  
> So log4net doesn't appear to be thread safe?  Any suggestions?
