Description

Device can not be accessed and we observe management daemon not running messages.

Symptoms

We observe below logs after login prompt and cannot go further.

Password:
--- JUNOS 19.4R3-S3.3 Kernel 64-bit JNPR-11.0-20210308.e5f5942_buil
could not open user interface connection: management daemon not running
Retry connection attempts ? [yes,no] (yes) yes
could not open user interface connection: management daemon not running
Retry connection attempts ? [yes,no] (yes) no


This is observed when we access SSH or console.
Since we cannot get into any prompt, we cannot restart management daemon using cli command or killing the process.

There is no known trigger identified, as we might not know when the device landed in the error condition. 
We have not observed any impact for passing traffic. Impact would be for accessing the device.

Solution

Power cycle the device to restore.
