Event ID 2137 in Passive Mailbox server

Hi,

I used Exchange 2010 in my environment. I have 2 mailbox server and 1 DB it has configured in DAG

DB1 is active in MBX01 and its healthy copy is availble in MBX02

I am getting in 2137 events in MBX02 server. I know DB1 is active in MBX01 server, MBX01 not able to truncate log files.

RPC request to the Microsoft Exchange Information Store service for log truncation failed for database Mailbox Database DB1Error: 4294965485.

I enabled full backup once a night per day. Why Exchange servers trying to truncate log files and showing this warning?
