Hello,
on security gateway R81 which I use as vpn ipsec peer I'am having problems with running out of memory on the active node. Memory decreases with a straight line down regardless of resource usage during the day. At some point all VPNs go down and I think memory exhaustion is the cause.
[Expert@VpnGW-member-b:0]# vpn tu tlist
Failed to get tunnels from instance 0.
