ike phase 1 lifetime, asa with netscreen

[pawel1942]

Hi all

Ipsec, L2L, in configuration I set 8h, on both side

IKE Peer: x.y.z.w

Type : L2L Role : initiator

Rekey : no State : MM_ACTIVE

Encrypt : 3des Hash : SHA

Auth : preshared Lifetime: 28800

Lifetime Remaining: 24897

but in logs, keys are changing in every 6 hours:

Jun 6 11:17:46 masterasa Jun 06 2009 11:17:46: %ASA-4-713903: Group = x.y.z.w, IP = x.y.z.w Freeing previously allocated memory for authorization-dn-attributes

Jun 6 17:17:46 masterasa Jun 06 2009 17:17:46: %ASA-4-713903: Group = x.y.z.w, IP = x.y.z.w, Freeing previously allocated memory for authorization-dn-attributes

Jun 6 23:17:46 masterasa Jun 06 2009 23:17:46: %ASA-4-713903: Group = x.y.z.w, IP = x.y.z.w , Freeing previously allocated memory for authorization-dn-attributes

Jun 7 05:17:47 masterasa Jun 07 2009 05:17:47: %ASA-4-713903: Group = x.y.z.w, IP = x.y.z.w, Freeing previously allocated memory for authorization-dn-attributes

Someone knows what's reason of that ?

thanks

i've never seen that before, especially if the lifetime is the same on both sides.

what is the output of "show isa sa detail" on the cisco equipment, and the equivalent output on the other hardware?
