Description

Currently we are facing some issues with the log4net configuration in our project. I am looking for help on this.

We are getting the following error in the log4net log file:

Error: Probable I/O race condition detected while copying memory. The I/O package is not thread safe by default. In multithreaded applications, a stream must be accessed in a thread-safe way, such as a thread-safe wrapper returned by TextReader's or TextWriter's Synchronized methods. This also applies to classes like StreamWriter and StreamReader.]

We are using the rollinglogfileAppender with the rolling style as "Date" and the locking model as "log4net.Appender.FileAppender+MinimalLock".

When nearly 250 users in our application tries to write to the log file it is coming with the above error message.

Any help is greatly appreciated.
