I used to think that, but in fact processes that are blocked in disk i/o (the ones in "D" state) do count in load average. So the load average of 12 in this case probably means processes writing to the disk. >From another e-mail showing several (12?) processes BackupPC_dump and BackupPC_nightly in "D" state, those should be the reason why this box stays with a load average of 12 during the night. >From those observations, it seems to me that the bottleneck in this case is disk I/O. Stephen, it seems strange to me that there are 8 BackupPC_nightly processes running, have you increased $Conf{MaxBackupPCNightlyJobs} from 2 to 8? I would suggest you start by setting $Conf{MaxBackupPCNightlyJobs} back to 2 or even to 1. If you set it to 1 and it can't finish its job in 24h, then increase $Conf{BackupPCNightlyPeriod} to 2 or 4 so that only 1/2 or 1/4 of the pool is processed each night.
