How to debug Redis random resets?

Question

I have a Redis server, running from docker-compose, used as a backend for Python's requests_cache lib.

Recently, Redis started to reset itself (Reason? Maybe I have more data cached than before ~3GB).

How to debug it better? What could be the reason of what seems like random resets? Docker-compose is being run on a 64GB laptop.

My config

port              6379
# daemonize         no
save              60 1
bind              0.0.0.0
# tcp-keepalive     300
dbfilename        grabtracker_redis_dump.rdb
dir               /data
rdbcompression    no
loglevel          debug

Errors from my app:

{"exception": "ConnectionError(\"Error while reading from redis:6379 : (104, 'Connection reset by peer')\")", "level": "error", "ts": "2022-04-18T10:51:54.957521Z"}
{"exception": "ConnectionError('Error 111 connecting to redis:6379. Connection refused.')", "level": "error", "ts": "2022-04-18T10:51:54.978355Z"}

And this is Redis output (I assume it is debug log level already):
