I managed to trigger this one on a Fedora installation too.  I guess
someone did grep for something inside /proc ...

  $ grep 0 /proc/sys/net/ipv6/neigh/default/retrans_time
  $ dmesg | tail -n1
  [61022.270399] process `grep' is using deprecated sysctl (syscall) net.ipv6.neigh.default.retrans_time; Use net.ipv6.neigh.default.retrans_time_ms instead.

It's not caused by 'grep' itself, but as 'grep' was looking at a sysctl
parameter which is now deprecated - this triggered the warning you saw.
