would you mind providing details and a decoded crash backtrace?

The CAN logging queue may saturate, so you lose some frames, but it
should not crash. I've just fed 11.000 frames into a vfs crtd logger
with 10 ms interval without issues:

OVMS# can log stop
Stopping all loggers
I (572602) canlog-vfs: Closed vfs log '/sd/can.crtd': total messages:
11261, dropped: 0, filtered: 0 = 0.0%
