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:

IKE session establishment timed out [AM_WAIT_DELETE], aborting!


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
