Hi, Hard to say what happens there but it might be that ldp/vls (the shims on top of vcl) do not handle properly whatever nginx does when it tries to reload. In particular, if it involves an exec syscall, we probably lose state and can’t recover.
As for the leak, what version of vpp/vcl are you using? Can you try with something recent like 22.02?
