had this happen to me on a box. pretty sure its was caused by using
crconf* with wrong arguments/multiple times so this should be
ipsec/crypto (pcrypt) related. unfortunately i don't have time right
now or more information..but i will get back to this.

*crconf add driver "pcrypt(authenc(hmac(sha1),cbc(aes)))" type 3
