You ran out of local memory. From a fast looking, I saw these:

pawn Код:

str[4848]
dialogMsg[5000]

and a couple of 2048. You must reduce those and it's recommended to declare big local strings with "static" instead of "new".

As for OnPlayerEnterCheckpoint callback, a function that was called in it with 1 parameter and its value of 400 caused the run time error 4. If there isn't much of code to it post it otherwise compile with debug info: https://github.com/Zeex/samp-plugin-...ith-debug-info
and get the line and more information.
