Remote VPN issue with 3020 Concentrator

Hi friends,

Just a strange issue on VPN Concentrator 3020.

There is an issue with remote vpn. It works perfectly fine but fails intermittently (sometimes after a day or two). Thinking that it may be a bug, i upgraded to 4.7 code but the same issue persists but probably less often.

But after i restart the concentrator, it works perfectly fine.

The following is the snippet of the filterable event log during the failure:

17034 08/06/2007 07:58:45.390 SEV=4 IKE/52 RPT=14

Group [clientvpn] User [yousifh]

Please let me know for any further directions in this regard.

Note: There is a site to site VPN also configured but that works perfectly fine.

Thanks a lot
