So on my 5540 i have a tunnel to a remote sonicwall. Remote end networks are data: 10.175.1.0/24 and voice: 192.168.178.0/24
Tunnel is up and passes traffic and from my end (Cisco ASA) there are no issues.
The admin on the other end sends me these log entries:
09/06/2013 06:29:30.000
Tunnel Down. policy 2(Hosted),

x.x.x, inSpi 0x9f520c5d, Reason

which is apparently happening every 40 to 80 minutes. Obviously just a blip.
And i confirm that on my end the SPI changes, but i dont really see an outage. Sonicwall help so far is less than stellar so i figure I'll ask the real experts even though I truly believe it's a sonicwall, or Fios modem issue, on their end.
thanks for any insights.
