Global Cooldown

One player is receiving a message saying that the global cooldown limit has been reached and a signal is being returned.
Other players can call in a helicopter without any problems when they throw, but this is the only player experiencing this issue.
They're normal players, so there's no difference in permissions or anything like that.
Please tell me why this is occurring.
Also, is there a log file somewhere that manages the cooldown times for teams and individual players? (For example, under /data)
I'm guessing that the fact that the player is throwing something is recorded there, causing this issue, but I can't find any such log data. I'm wondering where it's managed.
