Description

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
