Re0: Watchdog Timeout only when accessing webGUI
So heres a weird problem that has kept me on 1.2.3 release for the last few years.
I have a machine and the onboard nic (LAN) is Re0. When i try and access the web gui, the interface stops responding to pings for aprox 5 - 15 pings. it then bounces back and works fine and normal. The interface works fine and normal, unless i go to the web gui. I unfortunately cannot swap out the onboard card.
turning off https seems to have helped, but it still does it sometimes. Seems random. but usually when i am clicking around things in the webgui. (for instance dhcp log caused this one).
Here is an excerpt from system log.

Jul 14 14:38:45 sshd: Accepted keyboard-interactive/pam for root from IPADDRESS port 51657 ssh2
What is printed to the console is "re0: watchdog timeout" when the failure occurs.
machine is Intel(R) Pentium(R) 4 CPU 2.80GHz 1gb ram. p4p800 i believe
I should also say that the problem did not occur on PFSENSE 1.2.3 which I am doing a upgrade install from. Current version is 2.0.1-RELEASE (i386)
I can repeatedly make the problem occur by going to PFtop. So its something about heavy usage by the webgui i think… Wereas just watching the graphs on the pfsense dashboard page is fine for hours.
Anyone heard of anything like this? any tweak I could make the the web gui? its nice to be able to use it!!
That's a common issue with some Realtek NICs, kind of surprised you didn't see it on 1.2.3 as that exact issue has been reported by some for ages. Best I can offer would be to try a 2.1 snapshot since that newer FreeBSD base has a newer re driver which I know has fixed a number of issues but no idea on that one in particular.
Ended up using a PCI dual nic card (2 interfaces on one card) that i had lying around. I am just going to disable onboard.
maybe they will fix in 2.0.2 if there is s snapshot. oh well!
