SYMPTOMS

Backup stops because of a communications error.

Back to the top

When backing up to NULL or buffering the read bytes from HRBackupRead, the client and server may stop responding (hang) while waiting on each other. A communications error will be produced, causing the backup to be halted.

This problem is seen more often in single processor environments than in multi-processor environments.
