High Guest CPU causing High Host CPU

Not sure which board to post on, please let me know if there's a more appropriate one.

We have a number of RHEL VMs running docker in a client environment. Client manages ESXi, VM builds etc.

Client has reported that one of our VMS is running at 99% CPU over a period of time (big data workload), and that this is causing knock on CPU issues on the ESXi host.

I would have though the Hosts job was resource abstraction and management, and that Guest resource usage should not affect either other guests or the host ? I have little information about the hardware layer, version of eSXi but can probably get this if required.

Am I misunderstanding, or is this a configuration issue or similar - or something else entirely ?

Many thanks
