【22.03SP2】【redis】在redis-benchmark测试 5000并发时，会出现call_alloc_fail

**【环境信息】**
双端物理机，并在其中一个物理机上创建ovs+dpdk组网的vm
openeulerversion=openEuler-22.03-LTS-SP2
compiletime=2023-06-29-19-26-48
gccversion=10.3.1-37.oe2203sp2
kernelversion=5.10.0-153.12.0.92.oe2203sp2
openjdkversion=1.8.0.372.b07-1.oe2203sp2
[root@openEuler mysql]# rpm -q gazelle
gazelle-1.0.2-7.aarch64
[root@openEuler ~]# rpm -q dpdk
dpdk-21.11-50.oe2203sp2.aarch64

**【问题复现步骤】**，请描述具体的操作步骤
在vm端，启动redis-server LD_PRELOAD=/usr/lib64/liblstack.so GAZELLE_BIND_PROCNAME=redis-server /root/redis-server ${redis_conf}
gazelle配置如下
```
dpdk_args=["--socket-mem", "2000,0,0,0", "--huge-dir", "/mnt/hugepages", "--proc-type", "primary", "--legacy-mem", "--map-perfect"]

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=238

# 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="1"

#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="192.168.33.33"
mask_addr="255.255.255.0"
gateway_addr="192.168.33.1"
devices="52:54:00:5a:fc:ed"

#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=0
udp_enable=0
```
在物理机客户端使用redis-benchemark测试5000并发的set性能
./redis-benchmark -h 192.168.33.33 -p 6379 -c 5000 -n 10000000 -r 100000 -t set
之后再测试
./redis-benchmark -h 192.168.33.33 -p 6379 -c 5000 -n 10000000 -r 10000000 -t get
清除数据库
redis-cli -h 192.168.33.33 -p 6379 -e "FLUSHDB";
再测试12线程的set和get性能
./redis-benchmark -h 192.168.33.33 -p 6379 -c 5000 -n 10000000 -r 100000 -t set --threads 12
./redis-benchmark -h 192.168.33.33 -p 6379 -c 5000 -n 10000000 -r 10000000 -t get --threads 12

**【实际结果】**，请描述出问题的结果和影响
gazelle会打印如下信息
