I have question about RAM consuptions of VPN service. We have established IKEv1 VPN tunels with our customers. All work fine,but during autumn, it started to generate some problems with free RAM. After start service consume about 500 000KB. But about one week later system reports that have more than 80 (sometime 90 %) of system memory used. After restart VPN service, RAM system usage fall to 30 - 40 %. If we didnt restart this service, in about one week later system becam unstable and unusable.
We have F180 model with curent FW. Is this normal behavior, or there is any problem with releasing memory. As i said, about one year later, we have same configuration and system works many weeks without restart.
