The error is: "MBUF: error setting mempool handler" I have a multi-node NUMA system and I get the exact same error when trying to allocate the memory from the different nodes.  The bootstrap parameters I use to reserve huge-pages are: "default_hugepagesz=1G hugepagesz=1G hugepages=32" If I check the available huge-pages in my systems they look Ok (see below). fromm:~/:[130]# cat /proc/meminfo  MemTotal:       263470432 kB MemFree:        228408660 kB MemAvailable:   227792692 kB Buffers:            2148 kB Cached:           229132 kB SwapCached:            0 kB Active:           113424 kB Inactive:         150148 kB Active(anon):      33508 kB Inactive(anon):     1912 kB Active(file):      79916 kB Inactive(file):   148236 kB Unevictable:          80 kB Mlocked:              80 kB SwapTotal:       2104316 kB SwapFree:        2104316 kB Dirty:               624 kB Writeback:             0 kB AnonPages:         33216 kB Mapped:            60232 kB Shmem:              2388 kB Slab:             185240 kB SReclaimable:      46320 kB SUnreclaim:       138920 kB KernelStack:       22592 kB PageTables:         3000 kB NFS_Unstable:          0 kB Bounce:                0 kB WritebackTmp:          0 kB CommitLimit:    117062316 kB Committed_AS:     241992 kB VmallocTotal:   34359738367 kB VmallocUsed:           0 kB VmallocChunk:          0 kB HardwareCorrupted:     0 kB HugePages_Total:      32 HugePages_Free:       32 HugePages_Rsvd:        0 HugePages_Surp:        0 Hugepagesize:    1048576 kB DirectMap4k:      317756 kB DirectMap2M:    11014144 kB DirectMap1G:    258998272 kB Any idea / help would be much appreciated.
