Full or Incremental Phase Error: Can not read response from server

Scenarios

During a full or increment migration or synchronization, an error is reported, and the log information is as follows: service LOGMANAGER failed, cause by: Can not read response from server. Expected to read 4 bytes, read 0 bytes before connection was unexpectedly lost.

Possible Causes

The possible causes are as follows:

• The network bandwidth between the DRS replication instance and the source database is too small or unstable.
• The source database is overloaded.

Solution

Contact the source database administrator to check the source database load and check whether packet loss occurs on the network between the source database and the replication instance.
