I'm getting these errors on an IPSec tunnel I have created. The tunnel
working but it sometimes does not reconnect after the IPSec tunnel times
out and has to rehash the encryption.

Oct 28 09:06:15 	racoon: ERROR: isakmp.c:1073:isakmp_ph2begin_r():

Oct 28 09:06:15 	racoon: ERROR:

Does anyone know what these errors mean. I would greatly appreciate it.
