This message indicates that when the VPN re-negotiates , it could nort establish the tunnel in Data Plane since it already have a active tunnel in Data Plane for same SA .
generally this message comes when there is an active tunnel at one end and the other end tried to re-negotiate , when its hard life timer expires .
Please check if you do see tunnel flaps related to this tunnel . If not , you can ignore this . But if you do see an impact on this tunnel . Its adviced to opena JTAC ticket to confirm if this is software related issue ( PR ) .
Please Mark My Solution Accepted if it Helped, Kudos are Appreciated too .....
Thanks for you response can you please advice, as you said one tunnel is active and still the other one is inactive may be bcz its hard timer expires. So is it possible that its because of the some timer mismatch, or is it possible to modify some timers in order to make this issue fix.
Tunnel interfaces flaps sometimes and sometimes they dont.
