My application is using a c # class FileLogTraceListener log log, USES is multithreaded, set LogFileCreationScheduleOption. Daily used to generate a new log file every day, logging is normal, when I change the system time (i.e., produces new log files), will throw an error, as shown in figure,
I think is a bug, I check the source code can be found when calling CloseCurrentStream () function, m_Stream will be set to null, the error caused by FileLogTraceListener class said on MSDN is thread-safe, it seems not so, do you think what reason be?
