We have some CUCM/CUC on 10.5 and some are on 11.5 , the backup intermittently fails with ERROR: Unable to transfer the tar file over SFTP channel as currently configured SFTP server does not support output stream, Backup Completed. We’ve verified the backup configurations , tried to restart DRF agents, reset scheduler etc.…, but backup keeps failing. Manual backup normally go through with no issue. Out SFTP is CoreFTP.
There was a thread for similar issue mentioned it could be hitting a bug CSCul44464, but it seems fixed for version above 10.0. wonder if anyone could help to identify this is hitting the same bug. Any input is appreciated.
DRF trace collected and attached.
