Summary0001004: Very high cpu usage on Debian stretch
DescriptionEach time on consolidation we se a load of up to 18-20 (on a 6 cores machines).

There are about 20 backup clients on this machine in total. This is a backup server with sd only, the director is somewhere else.

This seems to have started pretty recently, there are 3 possible causes I can think of:

- Bug in newer bareos version
- Bug because of kernel update (less likely I would think)
- Extra backup clients, but it has grown pretty slowly and I don't think we saw such high usage before


Steps To ReproduceUse consolidation for about 20 clients on single SD, please see screenshot with perf top.

htop shows load of about 18-20 and high cpu usage on a couple of bareos-sd processes.
