Replication failed

Hello all,

We had 1 M x 4 slave server streaming replication using Postgres 10. Was working successfully for long time.

Suddenly all replication servers got failed and getting following message.

2020-12-17 22:24:32 +04 [1587]: [357-1] db=,user=LOG: invalid contrecord length 2722 at AEA/A1FFF9E0.

Requesting help for identifying root cause.

Thanks
