Memory consumption

[mimino]

Hey guys,

I've been running opnsense on my brand new J3355 box for a couple of weeks now, so far so good. One thing I'm noticing is the memory usage grows over time. It started at 10% upon boot up, after 17 days of up time it is now at 18%. I've been monitoring it for 5-6 days now and it's raising gradually. I do have IDS running, and my adblock list for DNS Resolver is quite big too. Plus the firewall rules from FireHOL. Could this be the cause? Is this normal? I'm not worried just yet since 8 Gig will hopefully never be exhausted, but at some point it might require a reboot to reclaim the memory. Thanks in advance.
