 As you noted, this is a duplicate of other PRs and should be closed.
 The problem is that your system workload caused the system to run out
 of KVM (kernel memory).  The solution is to increase the amount of KVM:

 I'm confused about what you're claiming here.  This option allocates
 400M of KVM (default is 320, so this is an increase and will provide
 your kernel with a bit more memory with which to work).  If 400 is
 still too low, try a larger value.
