Crash application après commande console répétée

[Gz']

Bonjour,

J'ai un petit soucis, je développe ma première application en obj-c/cocoa. Mais j'ai un petit soucis, elle crash tous les jours à ± la même heure. En gros je lance l'application le matin quand j'arrive au boulot et plante vers 17h.

L'application lance une commande console toutes les x minutes utilisant la méthode suivante:

- (NSString*) executeCommand: (NSString*)cmd: (NSArray*) args
{

	NSLog (@"CMD: %@ %@", cmd, [args componentsJoinedByString:@" "]);
	
	NSTask *task = [NSTask new];
	[task setLaunchPath:cmd];
	[task setArguments:args];
	
	NSPipe *pipe = [NSPipe pipe];
	[task setStandardOutput:pipe];
	
	[task launch];
		
	NSFileHandle *file;
        file = [pipe fileHandleForReading];
	
	NSData *data = [file readDataToEndOfFile];
	
	
	[task waitUntilExit];
	
	NSString *string = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
	NSLog (@"RESULT: \n%@", string);
		
	return string;
}

Je débute en obj-c/cocoa donc il y a sûrement quelque chose qui m'échappe, si quelqu'un a une idée. L'application utilise le garbage collector.

Le crash log:
