VPN Tunnel going down - after rekeying

[D@1984]

I have a vpn connection between a cisco ISR and Azure gateway which goes down every few days. I had a look at the logs and the rekeying seems to cause it:

Received request to rekey an IPsec tunnel; local traffic selector = Address Range: 0.0.0.0-255.255.255.255 Protocol: 256 Port Range: 0-65535 ; remote traffic selector = Address Range: 0.0.0.0-255.255.255.255 Protocol: 256 Port Range: 0-65535

Does anyone know how to fix this? could it be a misconfiguration? 

Thanks
