I have a couple of L2L tunnels on a ASA 5510 firewall and from time to time (2 to 7 days) all the tunnels go down:
sh crypto isakmp sa
Active SA: 2
Rekey SA: 0 (A tunnel will report 1 Active and 1 Rekey SA during rekey)
Total IKE SA: 2
1 IKE Peer: x.x.x.x
Type : L2L Role : initiator
Rekey : no State : MM_WAIT
The issue doesn't resolve until I reboot the firewall.
Could this be a hardware problem? Where should I look on the firewall for more info?
