Article ID: KB36092 KB Last Updated: 09 Apr 2021Version: 3.0
Summary:

During a Virtual Chassis (VC) global switchover on MX Series devices, the following authd logs will be seen on the new VC primary chassis' primary Routing Engine for a few seconds.

Jul  7 17:04:43.623 2020  router-member1-re0 authd[6509]: %DAEMON-3: db env state is invalid 6, re-init
Jul  7 17:04:43.623 2020  router-member1-re0 authd[6509]: %DAEMON-3: Attempting to close SDB while DOWN

This article explains that these logs indicate a transition state and are expected during a VC global switchover with no known service impact.

 

Symptoms:

When you perform a VC global switchover on member0-re1 (the VC primary chassis' primary RE):

{master:member0-re1}
router-member0-re1> request virtual-chassis routing-engine master switch         
Toggle mastership between routing engines ? [yes,no] (no) yes
Jul 07 17:04:41

The new VC state changes to below:

member0-re0 - Backup chassis' master RE (VC-Bm) 
member0-re1 - Backup chassis' backup RE (VC-Bb) 
Member1-re0  - Master chassis' master RE  (VC-Mm)   <<<< New VC primary
Member1-re1  - Master chassis' backup RE  (VC-Mb)

Observe the following logs on Member1-re0, which is the new primary chassis' primary RE:

Jul  7 17:04:41.999 2020  router-member1-re0 authd[6509]: %DAEMON-3: db env state is invalid 6, re-init
Jul  7 17:04:41.999 2020  router-member1-re0 authd[6509]: %DAEMON-3: Attempting to close SDB while DOWN

Jul  7 17:04:46.935 2020  router-member1-re0 authd[6509]: %DAEMON-3: db env state is invalid 6, re-init
Jul  7 17:04:46.935 2020  router-member1-re0 authd[6509]: %DAEMON-3: Attempting to close SDB while DOWN

 

Cause:

The logs indicate a transition state during VC global switchover wherein authd (the authentication daemon) is trying to connect to sdb (the subscriber database). These messages will stop when the transition is complete.

 

Solution:

No action is required because these logs are expected during VC global switchover and there is no service impact. They are informational and can be safely ignored.
