What "Already logged in" actually mean?

[DumahBrazorf]

Hi,
I have multiple pcs connecting to one account. Every pc save its session token to avoid loggin in every time. If the token expires there's a new login.
There's some pcs that many times got an "Already logged in" error message when issuing MegaApiClient.Login(thetokenpreviouslysaved). What it means? What should i do o have done before to avoid this error?
Maybe more pcs are accessing the account in that precise moment?
Thanks.

I never saw this error. Do you call the Logout() method in your code after a session?

Mmm, i don't.
I didn't do it thinking it would have flooded the server with too many logins...
Let me change something in my code...

Ok i can't logout or the sessionId will be useless (badsessionid at the next login with masterkey and sessionId) and then i have to login with username and password. If you login too much often with user/pw mega will lock you out.

So "Already logged in" probably mean i'm already using that masterkey+sessionId and doing something with another instance.
I have to check my code to ensure the upload function is not called twice or more.
