Hi,

We are using log4net in conjunction with NUnit and MSBuild.

We are testing a cache implementation which requires the usage of
log4net and Common Logging (from the Spring Framework).

When running unit tests, each invocation of a test case which causes a
log entry to be created in turn causes log4net to blow up on the trace
with the following:

log4net:ERROR [TraceAppender] Failed in DoAppend
System.Threading.ThreadAbortException: Thread was being aborted.

System.Diagnostics.StackTrace.GetStackFramesInternal(StackFrameHelper
sfh, Int32 iSkip, Exception e)
   at System.Diagnostics.StackTrace.CaptureStackTrace(Int32 iSkip,
Boolean fNeedFileInfo, Thread targetThread, Exception e)
   at log4net.Core.LocationInfo..ctor(Type

loggingEvent)
   at log4net.Appender.TraceAppender.Append(LoggingEvent loggingEvent)
   at log4net.Appender.AppenderSkeleton.DoAppend(LoggingEvent
loggingEvent)

Can anyone explain this at all, as I don't know log4net internals at
all?  It is currently causing our build to fail as MSBuild interprets
this as a failure condition.

Many Thanks,
