Hey guys, I've encountered another issue with my FreeNAS 9.x machine and was in need of some help and guidance. I've had a few issues since upgrading from 8.x to 9.x and had everything ironed out for a few months, until recently of course.
The issue seems to be my network card interface flapping. Essentially, I open a few of the web GUIs via a browser (about 5 GUIs including FreeNAS) and the connection dies. After some troubleshooting I determined it was the network interface dropping. I let a ping run until I get a reply back and the FreeNAS machine is reachable again. I may or may not be able to access the GUI again though as the connection will drop once I try and connect. It's really hit-or-miss.
Not sure what to pinpoint as the culprit thus far. I'm on vacation as I've figured this issue out so I haven't spent much time getting my elbows dirty. Thought I'd ask for some feedback before getting home in a few days and digging into it. I don't believe it to be a cabling issue due to the issue happening under some load on the FreeNAS box. I haven't quite ruled out my switches but they're lower on the list (a couple of gigabit, unmanaged switches).
I've included some information below that may assist in this endeavour. Cheers!
