**【环境信息】**

双端物理机，并在其中一个物理机上起一个vm（virtIO+nvme直通组网）

[root@openEuler ~]# cat /etc/openEuler-latest

openeulerversion=openEuler-20.03-LTS-SP3

compiletime=2022-01-01-11-20-51

gccversion=7.3.0-20211123.43.oe1

kernelversion=4.19.90-2112.8.0.0131.oe1

openjdkversion=1.8.0.312.b07-10.oe1

[root@openEuler ~]# rpm -q dpdk

dpdk-19.11-31.oe1.aarch64

[root@openEuler ~]# rpm -q gazelle

gazelle-1.0.2-2.aarch64

**【问题复现步骤】**

服务端已预置64*10000000的sysbench测试数据

1. vm端启动mysqlLD_PRELOAD=/usr/lib64/liblstack.so GAZELLE_BIND_PROCNAME=mysqld stdbuf -oL numactl -C 0-6 /usr/local/mysql/bin/mysqld --defaults-file=/root/my.cnf --bind-address=124.88.69.54

```

dpdk_args=["--socket-mem", "1024,0,0,0", "--huge-dir", "/mnt/hugepages-lstack", "--proc-type", "primary", "--legacy-mem", "--map-perfect", "-d", "/usr/lib64/librte_pmd_mlx5.so" ]

use_ltran=0

kni_switch=0

low_power_mode=0

#needed mbuf count = tcp_conn_count * mbuf_count_per_conn

tcp_conn_count=1500

mbuf_count_per_conn=138

# send ring size, default is 32, max is 2048

send_ring_size = 32

# 0: when send ring full, send return

# 1: when send ring full, alloc mbuf from mempool to send data

expand_send_ring = 0

#protocol stack thread per loop params

#read data form protocol stack into recv_ring

read_connect_number = 4

#process rpc msg number

rpc_number = 4

#read nic pkts number

nic_read_number = 128

#each cpu core start a protocol stack thread.

num_cpus="7"

#app worker thread bind to numa in epoll/poll.

app_bind_numa=1

#app main thread affinity set by dpdk.

main_thread_affinity=0

host_addr="124.88.69.54"

mask_addr="255.255.0.0"

gateway_addr="124.88.0.1"

devices="52:54:00:d9:d8:00"

#0: use rss rule

#1: use tcp tuple rule to specify packet to nic queue

tuple_filter=0

#tuple_filter=1, below cfg valid

num_process=1

process_numa="0,1"

process_idx=0

#tuple_filer=0, below cfg valid

listen_shadow=1

udp_enable=0

```

2.客户端执行512并发sysbench测试

numactl -C 16-95 sysbench --db-driver=mysql --mysql-host=124.88.69.54 --mysql-port=3306 --mysql-user=root --mysql-password=123456 --mysql-db=sbtest --table_size=10000000 --tables=64 --time=120 --threads=512 --percentile=95 --db-ps-mode=disable --report-interval=1 --range_selects=0 --skip-trx=1 oltp_read_only run

**【实际结果】**，请描述出问题的结果和影响

当"--socket-mem", "1024,0,0,0"中内存小于或者等于1024时，发生coredump，大于1024时则不会发生coredump
