Log Reader Agent is not able to read Transaction Log of Publisher database.

Hi,

There is no restore or change in recovery model or detach-attach action performed on my production database but still I am seeing below error message from Log Reader Agent-

Error messages:
The process could not execute 'sp_repldone/sp_replcounters' on 'ProdInstance'. (Source: MSSQL_REPL, Error number: MSSQL_REPL20011)
Get help:

An error occurred while processing the log for database 'MyDatabase'.  If possible, restore from backup. If a backup is not available, it might be necessary to rebuild the log. (Source: MSSQLServer, Error number: 9004)

The process could not set the last distributed transaction. (Source: MSSQL_REPL, Error number: MSSQL_REPL22017)
Get help: The process could not execute 'sp_repldone/sp_replcounters' on 'ProdInstance'. (Source: MSSQL_REPL, Error number: MSSQL_REPL22037)

Note- CheckDB on production and distribution database executed successfully. Also, I need subscriber to be a true copy of publisher so I think sp_replrestart is not an option for me.

My question is how to resolve this issue? I am thinking that reinitialization should resolve the problem but what if this is not going to resolve? Do I need to reconfigure the transaction replication? Please sugegst.
