So... there are many questions to your query.
You could look at your system logs and determine the cause of the why the VPN goes down.
Now, the default ike crypto file is configured to renegotiate at 8 hours...
Can you (or have you enabled) IKEv2 to take advantage of the higher timer?
Have you confirmed IF the OCI can be configured to increase its timer, beyond 8 hours?
Have you looked at your global counters to confirm if you are seeing fragmented traffic?
Do you have a Zone Protection profile (getting warmer...) that may be dropping fragmented traffic?
These are what I would start to look at first.
Keep us in the loop. 😛
