When using IKEv2 on an m7i with an adaptive services module running 15.1R7.9 the VPNs aren't stable, and I am getting these strange log messages:
ikev2_state_error: [9970c00/a41d400] Negotiation failed because of error Out of memory (65537)
Neither the RE or the adaptive services module is low on memory. The VPNs come back up, but they flap quite a bit. Also to note, these memory errors are only seen with 'route based' type VPNs, i.e. ones with 0.0.0.0:0/0.0.0.0:0 traffic selectors, not VPNs with explicit networks described for phase 2. Any idea what these memory errors mean? I don't see these errors with VPNs that use IKEv1.
