Fix fatal error: evacuation not done in time problem

Tags : golang evacuation rlock lock

Encounter one of the strangest error messages in Go today regarding evacuation. Now, what the heck "evacuation" has to do with programming language ? Apparently it has something to do with locks.

This error message :

"fatal error: evacuation not done in time"

is caused by accessing a map from multiple go-routines and is not thread-safe.

Solution :

Check if the RLock or Lock is in proper place. Might need some fine tuning through trial and error.

p/s : This solution is applicable to the error message fatal error: bad state as well.
