Hi George,
I don’t have any issue with “show nat44 sessions” under heavy load (it just
print number of session for each NAT user/internal network IP, no sessions
details). Without core file analysis hard to say where is the issue.

Subject: [vpp-dev] The command "show nat44 sessions" occurs "worker thread
deadlock".
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!
Regards,
Geoge
