EX4100 losing network connection after a while (OS5)

Here are some of the old posts I found:

EX4100 becomes unresponsive, loses network

I never had this issue BEFORE I upgraded to OS 5. Now my EX4100 is hanging every few hours and only comes back after a power loss. First CPU and RAM go up to 100% and over 300 processes are started. Then after a while, the unit is just dead except for LEDs. No connection to anything, no buttons working. I tried hard reset (40s). I changed the cables, the power supply and the router. None of which worked. Anything I can do now?

EX4100 stops communicating and won't power off

I just bought an EX4100 16TB unit, and got it up and running with the public share, and an 8TB iSCSI target, using MPIO & 9000 byte packets size. It ran for about 7 hours before it stops communicating on the network; it does even respond to an ARP request. All lights are frozen, and the power button doesn’t work.

EX4100 Keeps disconnecting from the network - ANNOYING!

@dangernoodle, There are numerous posts already on this issue with no resolution from WD. Check out these posts… For some reason the EX4100 units periodically stop responding and the only way to get any life back in them is to do a power cycle by pulling the cord out and plugging it back in. I myself have to do the unit I have every 2-3 weeks. Got no idea why this happens and WD are not being forthcoming with a fix. Cheers, JediNite
