> This can be reproduced when we have 2 segments, each has 75gb, 15core. cluster memory-core ratio is 5gb per core, and then we trigger resource consumption by allocating and returning 256mb * 12 vsegs.
> (gdb) p *containerset
> $6 = {Allocated = {MemoryMB = 5120, Core = 1, Ratio = 0}, Available = {MemoryMB = 5120,
> Core = 0.99999999999999956, Ratio = 0}, Containers = 0x7ff07a93c870}
> (gdb) quit
> A debugging session is active.
