Master server overloade, memory full because of bpbkar process
Hi
I have a problem in my environment, where the Kernel from S.O is finishing bpbkar process. I contacted S.O Team and they told me that kernel is finishing the bpbkar because of high cpu utilization.
Recently I did the upgrade from NBU version 7.6.1.1 to 7.6.1.2. My environment is totaly for Vmware backups, almost one hundred VMs, and these runs on weekends.
When the backup windows starts, some backups completes with success, but most of backups fail, after the crash of bpbkar process
My Environment
Master Server Type: Vmware
Windows Server 2008 R2 Enterprise SP1
Processor 4 processors 16 cores
Memory 32GB
NBU Version 7.6.1.2
Attached some logs, below follow messages from event viewer. Can you help me?

Why not split the jobs over the week, by this I mean instead of having 1500 fulls runing on Fri, have 215 running fulls on Fri, 215 running fulls Sat, 215 running fulls Sun, 215 running fulls Mon and so on. For the days a group of clients is not running full, then run incremental.
I never understand why people run all the fulls at the weekend, it doesn't matter, as long as there is a full once a week, and incrementals the other days, then which day the full is is irrelvant.
This prevents hammering a system at a weekend and spreads the load out evenly.
