Bareos emails "*None*" - Director unable to authenticate with Storage daemon

[Joe]

Hi all,

we running Bareos in multiple instances while each is configured the same except for clients, jobs and of course FQDNs / IPs.

We are receiving emails generated by each Bareos instance with the subject *None*: *None* of *None* - *None* (Error).

15-May 04:11 backup01.example.com JobId 0: Fatal error: Director unable to authenticate with Storage daemon at "backup01.example.com:9103". Possible causes:
Passwords or names not the same or
TLS negotiation problem or
Maximum Concurrent Jobs exceeded on the SD or
SD networking messed up (restart daemon).

The message is from 04:11 but the email sent was from 08:52. The time I logged into the Bareos WebUI.

These emails are also being sent while jobs are running.

At first I set the connection in bareos-dir->storage to 127.0.0.1 and localhost but that generated way more emails than using an internal FQDN. So that reduced the amount of emails sent.

What is the exact reason for this message, please?

Here is our config (of hopefully all essential parts).

I forgot to mention that on each Bareos instance we are running more than 100 jobs succeed while only few fails (like 8) each day.

Hi all,

What apparently fixed our problem is adding 10 more connections to dir->sd and sd->storage than dir->director has.

This was taken from https://bugs.bareos.org/view.php?id=763.

Best regards
