Hello everyone,


When I use "show nat44 sessions" ,with the VM sends packtes to vpp do nat 
translate, the vpp will crash. 


The vpp shows below:


vpp#     show nat44 sessions
Connection closed by foreign host.


vpp# vlib_worker_thread_barrier_sync_int: worker thread deadlock
Aborted


My vpp version is :vpp v18.04.


In my opinion, I think that the "CLI command" can not be disposed under a large 
number of packets in processing.


Please give me some advice, thank you very much!




/etc/vpp# grep -v "#" startup.conf


unix {
  log /var/log/vpp/vpp.log
  full-coredump
  interactive
  cli-listen localhost:5002
  gid vpp
  exec  /etc/vpp/setvppinterface
}


api-trace {
  on
}


api-segment {
  gid vpp
}


cpu {
main-core 1
corelist-workers 4
}
dpdk {

        dev 0000:42:00.1

        vdev eth_bond0,mode=4,slave=0000:04:00.0,slave=0000:04:00.1
        vdev eth_bond1,mode=4,slave=0000:42:00.0,slave=0000:42:00.1
