EAP Update 1 - Losing WAN

So I updated to "Update 1" and now my fw pair loses the wan connection once a day at random.  Never had an issue before on V18. Anybody else having any issues like this?

I have a 310 V2 appliance (Pair In Active / Passive)

When the WAN goes down I can ping the appliance but not outside (WAN). That makes sense as the wan is down. 

I notice the memory utilization is very high. In fact our network monitoring alerts me to 90 percent o higher several times a day.  When I look at the memory graph I see something weird to me. Last line... The total, min, max, average and current is the same.  I have a hard time believing that is accurate???
