ATP500 and rekey time in phase1 for ipsec VPN tunnels

Hi

I have a IPSEC tunnel, the other side is a Sophos device. We have intermittent disconnections and the Sophos guy says that it's due a bad rekey time. The remote log shows:

"Received IKE message with invalid SPI"

They have the tunnel configured in Phase1 for SA LifeTime of 10800s with a re-key margin of 360s, but I can't configure the second one setting in the ATP500.

Which is the default re-key margin for an ATP500?

Regards
