Обсуждение: [ADMIN] could not access status of transaction

While configuring streaming replication on master(master already had 200gb data), I added the following changes

wal_level = hot_standby

max_wal_senders = 3

wal_keep_segments = 8

and restarted postgres.

I started getting error

could not access status of transaction 243368097

Could not open file "pg_multixact/members/433B": No such file or directory.

What steps should I take to recover from this.
