Thorsten Schöning resolved LOGCXX-309.
--------------------------------------
    Resolution: Cannot Reproduce

Because we are trying to reduce the backlog of open issues, I'm closing this one right now. The described environment in which the problem has been reported originally is pretty outdated these days and things might have been fixed already with a newer version of log4cxx and/or a new environment. If this concrete problem is still relevant for someone, feel free to reopen and provide the necessary details. Otherwise it's best to create a new issue describing the new environment and problem.

> I have encountered a stack overflow exception when trying to use log4cxx with multiple threads writing log messages. The logging code in my project is as follows for each thread:
> .....
> USES_CONVERSION;
> CString msg;
> msg.Format(_T("[%s] PACKET: checksum: %x [OK], timestamp: %llu, sync.time: %u, measurement: %u"), 
> 						m_sName, pDataMessage->CheckSum, pDataMessage->TimeStamp, 
> 						pDataMessage->ProfileMeasurement.SyncTime,
> 						pDataMessage->ProfileMeasurement.MeasurementNumber);
> LPCSTR lpszLogMsg = T2CA( (LPCTSTR)( msg.GetBuffer()) );
> LOG4CXX_DEBUG(logger_RPReceiverThread, lpszLogMsg);
> msg.ReleaseBuffer();
> .....
> I am using a single appender:
