Error description
After upgrading IBM Spectrum Protect Plus to 10.1.5, the number of VM backups running in parallel is less than expected. This can lead to longer backup times, overrunning the backup window. When this issue is encountered, all VMs on first ESX host will be scheduled to go. After these VMs are done with the backup, then the VMs on the next host will be scheduled, and so on so forth.
