map server crash after exiting an instance

[CyberDevil]

Hello everyone, I have a strange problem that I can't understand... a player told me that when he left an instance (I'm waiting for his answer to figure out what this is) the map server is crashed.
These are the log of the moment of the crash:

[03/Feb 17:12][Info]: [Instance] Destroyed 2.
[03/Feb 17:12][Error]: Server received crash signal! Attempting to save all online characters!
[03/Feb 17:12][Status]: Map-server #0 has disconnected.
[03/Feb 17:12][Status]: set users INFINITY : 0

Do you have any suggestions to give me for a first generic check?

...this is the player's answer on my server:

The istance was Old Glast Heim, I did it with a friend of mine and we were thrown out of the instance because it was finished the maximum time of 1 hour in which you can stay inside the instance... soon after it is crashed the map server!

The Old Glast Heim script is the original like this:

I see that there have been recent updates, could these updates solve this problem?
