Error description

  • If IPsec tunnels are configured but not loaded
in the kernel, the lstun command may hang in
an infinite loop, constantly printing the
message

IPv4 Tunnel ioctl failure.

This is most likely to happen after a Live
Partition Mobility (LPM) migration where the
source system has IPsec configured and the
lstun command is running while the migration
is taking place.
