Body: <p>I'm using PAMGuard to process some recordings and I keep having an issue where it is freezing. I'm trying to create an LTSA at the same time as using the GPL detector (for blue whale A/B calls). I have run just the GPL detector in the past without it stalling, but when I added the LTSA module, the software crashes after running about 24 hours of recordings. I know it's stalling because of the LTSA because PAMGuard throws a warning on the main panel of the software (see screenshot below). Is there anything I can do to fix how often it crashes? The files I am processing are sampled at 384kHz. I'm decimating them to 400Hz to run the GPL detector but I'm trying to create a full bandwidth LTSA. Is this just too much for PAMGuard to handle? See the second screenshot below for the DOS window</p>
