Change Jail Interior for testing purpose. SetPlayerPos to some place else. If player does crash this time, Your command has some problem which makes his crash and if it doesnt crash, means there is a bad object inside your jail interior.

make sure you are not using formating with SendClienMessage,
like,

Code:

 SendClientMessage(playerid, -1, "You are jailed for %d Mins.",time);

Use format for that.
