PHP/SQL script stops unexpectedly, works in debug - php

Question

I have a fairly long script that ran fine until last night (no changes made, that I know of).
The query that needs to be run is this:
$query = "INSERT INTO results SET
compId = ".$comp_id.",
eventId = ".$eventId.",
eventSession = '".$eventsession."',
driverId = ".$driverid.",
teamId = ".$teamid.",
position = ".$this->data['drivers']['position'][$i].",
raceTime = '".$racetime."',
laps = ".$this->data['drivers']['laps'][$i].",
pitstops = ".$this->data['drivers']['pitstops'][$i].",
engine = ".$engineId.",
tyres = '4',
sector1 = '".$sector1."',
sector2 = '".$sector2."',
sector3 = '".$sector3."',
fastestLap = '".$this->data['drivers']['bestTime'][$i]."',
grid = ".$grid;
// If debug is true then just var_dump but don't execute query
if ($this->debug) {
var_dump($query); echo '<br>';
}
else { // debug is false here, then not debug and run mysql query as usual
mysql_query($query);
}
I ran a debug/var_dump script that shows that all data is read correctly, and shows that the script correctly runs for each record in the dataset:
string(341) "INSERT INTO results SET compId = 8, eventId = 934, eventSession = 'P', driverId = 408, teamId = 142, position = 1, raceTime = '', laps = 9, pitstops = 0, engine = 57, tyres = '4', sector1 = '34.8867', sector2 = '35.8517', sector3 = '35.7191', fastestLap = '106.4575', grid = 0"

However, when not in debug, this only runs for the first record in the set. No matter what dataset I feed into.
I am at a loss at explaining what is going wrong or if there is anything that stops the script after the first instance (which is entered correctly).
Note: the original code is not mine and I no longer have access to the original developer as he left our group, so I am just basing myself of the current information. As mentioned earlier, this script has worked correctly until last night and no changes have been made to other parts of the code that may affect it.
Thank you for any help!

Answer 1

Issue resolved - the DB in which we were trying to add the rows had the ID field set to smallint. We had literally reached the limit of rows (65535) and therefore it was working on debug and not in real life.
