I think As of now u can't get xa't answer, but when problem hap'n again plz check the ISP side any errors at Internet router.Many of the site to site VPN hang issues are resolved after fixing the CRC errors that we were encountering on our Internet router. So you may check for such errors on your Internet router as well.
My internet router is a Cisco 887. I'm using ADSL line. During the problem, the internet is working fine. I don't restart the 887. Only restart the ASA5510 and the problem solved. Does you recomend that if it happen again check the CRC error at 887?
