It is used to keep active sessions in memory. However, it loadSession function in session.go was creating race condition.
cachedSessions = map[string]Session{} for _, s := range sList { Preload(&s) Preload(&s.User) cachedSessions[s.Key] = s }
This part was modfying a global variable(shared) and was causing race conditions.
So, I added a Read and Write Mutex Lock and protected its read and write access (can have multiple reads).

The code changes were tested locally on the system (with our own application) and they worked(succesfully able to do multiple logins at the same time)

Below is the error trace:
