you got some huge arrays declared (local inside a callback):

pawn Код:

new Array[MAX_PLAYERS][256];

or you got a bunch of if/else if's in a row.
to enlarge your stack/heap size, goto the pawno editors' menu "Build" > "Run options", search for the box "With these parameters...", and change the "-r" to "-r -S8192", or better "-r -S16384" when required.
