Networking stops sporadically

ccraig13
I've been running UTM 9 for about 6 months now. About a month ago I had to login at the console and reboot the system because I was unable to connect. Now it's starting to happen on a weekly basis.

The issue is that network stops working and I'm unable to ping the UTM or ping another device on the network from the UTM.

Hard drive usage is no where near it's limit and top shows no programs with high CPU usage (system is idle). System is also fully up-to-date. We don't do anything fancy and have only around 20 potential active connections. It was running fine all day but when I came into work tonight, it was down. Since no one else was here, it went down with only the CrashPlan backup running.
 
The hardware is brand new and very capable.
 
Any thoughts on this are greatly appreciated!

    get rid of the realteks and use either Broadcom or Intel devices.  Make sure the chipset is NOT 82573(V/L/E) though for the intel nics..[:)]
