VPN hanging issues....

I have two sites that are connected with a IPSec L2L VPN using ASA5520's. The main site is hosting our servers, callmanagers, unity, etc. The second site is mostly workstations and IP phones. During the week we haven't had any issues with the VPN. However, on the last two Mondays when people come back into the office the VPN has not been functioning properly. Last Monday when we came in the the isakmp sa was still up, but for some reason one of the ipsec sa's was hung. (We have a voice subnet and a data subnet. Traffic was going across for the data subnet, but no voice traffic was going across.) This Monday when we came in, the isakmp sa was up, and the ipsec sa's where up, but for some reason, no traffic was getting passed across the VPN. I cleared the isakmp sa, and everything came back up just fine. Any ideas?


Re: VPN hanging issues....

Probably, the issue with hardware related like more cpu cycles in the ASA's or less memory,otherwise it is related to vpn interesting traffic configuration in ASA's.
