Hm, I just did a run with 8k NFS packets, and the results are slightly different. There's only a single READDIR reply, fragmented over 3 IP packets. vg_include.h~51-kill-inceip still has a cookie of 1611747420, and vg_libpthread.vs is still the last entry returned, but it has a cookie of 0. As far as I can see, all the other cookies are unique. Trace attached.
