Hi,
From the logs, we can see there are two types of error for the MIB node failure. All the error occurred when the NMS Server backup device configuration file.
1. ErrorStatus=12, ErrorIndex=3
When the NMS Server backup the device file, the NMS server will deliver a task to the device and the device will use the MIB node to backup the file then send it to NMS Server. But due to frequent backup operation on NMS Server causing the device to exist the same task, appear this issue.

2. ErrorStatus=13, ErrorIndex=8
This means the CFG module of the device is busy, also due to frequent backup operation on NMS Servercausing device don’t finish the previous backup task and new task come from NMSServer, so appear this failure(device only can do one backup at the same time).

Therefore, please changes the server backup settings. Backups can be performed once a day at most. Typically, we set up a one-week backup.
And if there are several NMS Server, you need to set different backup times periodically.
