Probably interrupts generated while writing data from cache to disk.
But it's just a guess since I have no idea how much data or how fast
your computer is. You can also try to run volk_profile included in the
bundle to enable cpu optimized code.

You can try to play with various input decimation settings. PErhaps
you just need to reduce the IQ rate a bit.
