I have not changed file systems, though I have tried the recordings now
on three different file systems:
- ext4 (nvme drive)
- ext4 with dm-crypt full disk encryption (ssd)
- xfs (large SATA hard disk)
All three have yielded the same results.
Though the WAV file size limits idea is a solid one to explore. I am now
running a test capture in FLAC and will report back with those
results...

Hi list,
I am using jack_capture to record 2 inputs and 20 outputs going
through SuperCollider for a duration of between 30-45 minutes, using
the following command line:
jack_capture -f wavex -p supernova:* test.wav
This has worked well for my use case for several years. However, since
yesterday this command line fails to capture the entire recorded
performance, despite jack_capture showing the meters responding to the
audio correctly. Whenever the recording duration exceeds approximately
20 minutes, the output file will only contain the first 5-10
minutes. However, if we only do a 5-10 minute recording, the entire
recording is captured and saved properly.
Sounds like a file size problem? Something like a 2GiB or 4GiB related
limitation?
Have you changed file systems?
