Exit code 6 can happen if the audit daemon can't parse its configuration: https://sources.debian.org/src/audit/1:2.8.2-1/src/auditd.c/#L674
The routine to parse the configuration appears to have copious debug logging: https://sources.debian.org/src/audit/1:2.8.2-1/src/auditd-config.c/#L321 Did you get anything in /var/log/audit/audit.log that could explain what went wrong?
