A function was used inside OnGameModeInit and crashed the server due to an invalid file handle. Before reading from a file, make sure it's valid.

An example:

pawn Код:

new File: file = fopen(...);
if (file) // valid handle
{
    // code.. use fread, fwite and fclose inside here.
}

As for that function that used fread inside, you can find it by compiling with debug info. Re-compile, run the server and check the new logs. It should say its name in "#1 ... in ...(function name here)".
