pawn Код:

for ( new t; t < 1000; t ++ )
{
SetPlayerHealth( playerid, 50.0 );
SetPlayerHealth( playerid, 100.0 );
}

Put that in a command or something and test if it actually does kill the player randomly. I've never experienced such a problem though. (and I would test the method above, but I'm not on a computer with San Andreas)
