Queries made using reference jobs on the standby server may be canceled by jobs executed on the primary server.
To reduce the possibility of a job being canceled, specify as large a value as possible for the max_standby_archive_delay parameter in the postgresql.conf file.

Refer to "Handling Query Conflicts" in the PostgreSQL Documentation for details.
