Windows guests on Linux 64-bit host freezes intermittently

|Version:||VirtualBox 4.1.8||Keywords:||guest freeze cpu spike|
I have an Oracle Linux 5.6 Linux 64-bit host with VirtualBox 4.1.8 The host details: 16 cores 140 GB ram Disc controller: Raid,etc. 1 - 1GB Ethernet connection (motherboard NIC)
Currently, I have 5 VM guests, 3 Windows 2008 64-bit and 2 OL 5.6 64-bit
The host is not heavily utilized at this point.
What I am seeing is in the Windows Guest OS (accessed via Remote Desktop), if I do any type of activity the requires networking (i.e. Open FireFox, copy files to a mapped network share, etc.), then I see the CPU for that particular VM spike to 100%+ for a period of time (it varies but 1-3 minutes) and the guest is unresponsive (I have tested Remote Desktop and directly via the console).
The Windows Guest are bridged using Adapter 1: Intel PRO/1000 MT Server (Bridged adapter, eth1)
On the Linux Guest, I see similar, but the cpu spikes quickly and then drops within seconds.
I am not sure if the guest's are having a network contention issue on the host.
Each VM has a unique network MAC / hardware address
I am using the native VirtualBox Intel NICs
I see this behavior on a second Linux host with VirtualBox 4.1.6 as well and Windows 7 65-bit guests.
I have attached the VM log, I can provide whatever further debugging you require.
