IPSec tunnels down, can't get back up

[MattWray]

I had 4 of my tunnels go down over the weekend, I can't get them back up. I have verified with the ISP, and al seems to be fine on their end. The only thing I can find so far is in the log I receive this error under IKE SA's

#pkts no sa (send) 75

Any ideas on what to check? No configs were changed, so it is a mystery why they are down...

Thanks,

A couple more things, in the IKE SA monitoring in PDM, I can watch one tunnel try to come up. I see it appear with MM_SA_SETUP for a few seconds, then MM_KEY_EXCH, for a few seconds then it goes away all together. I am sure the keys are the same.

I'm not getting anywhere fast with this...

Well I figured it out. For some unknown reason, there was an issue with the pre-shared key. I reentered the keys and bounced all the routers and they came back up.

Maybe this can help someone else in the future...
