Jibri recording stopped after long time

Jitsi - in docker (this version: https://github.com/jitsi/docker-jitsi-meet ) on Host1
Jibri - in docker (same URL) on Host2, 5 instances.

ffmpeg records only sound. All works fine, but…
After starting record after long time (20-40 minutes) record crashes
I think because ffmpeg speed decrease (end of log):

Bitrate low (uses 50-110% of core), server have 8 cores.
What can be reason of ffmpeg crashes? How debug it?

Not enough RAM maybe?
