I386 p4 3.0ghz 1gb ddr memory, stops working after a while.

[elementalwindx]

I have the following packages:

anyterm
bandwidthd
Dashboard Widget: Snort
imspector
mailreport
nmap
pfBlocker-dev
snort
Strikeback
stunnel

I've upped my tables to 100 million.

I have dual wan single lan setup, setup with a round robin-like failover group. Over the night while I was sleeping I got these emails:

MONITOR: CenturyLinkGW has packet loss, removing from routing group

then

Gateways status could not be determined, considering all as up/active.

I notice the next morning I can come back and go to use the internet and I can go to websites fine, but when I go to try and use remote desktop it stops me, or if I try to login to the admin page it does not respond. Then if I power cycle the firewall everything is all better again and I can do everything correctly.

Can someone help me troubleshoot this?
