Aditional information

1. Ubuntu 18.04.6 LTS (Bionic Beaver)
2. Running a replicated cluster, observed that we are unable to connect successfully to keydb after some days. Same experience with the CLI tool at such times. The only option is to force a restart of the two server instances. I got this crash on both servers while performing the restart today.

This may be related to issue #537

The only additions to /etc/keydb/keydb.conf on this server follows, similar to the other one:

requirepass "7eTA19aAa1mZ6"
masterauth "7eTA19aAa1mZ6"

Should be fixed with 6.3.2, please re-open if you run into this again.
