2.2.4 to 2.3 dhcp no longer obtained until reboot

That shows it's sending traffic and not receiving anything. Do you have kern.ipc.nmbclusters configured in /boot/loader.conf or loader.conf.local? If not, add this line to loader.conf.local:

kern.ipc.nmbclusters=1000000

and reboot. With e1000 NICs I doubt you're exhausting mbufs, but that's a potential symptom in that circumstance.

If it happens again with that, try running (where em1 is your LAN NIC, replace accordingly):

ifconfig em1 down
ifconfig em1 up

and see if that does anything. That may narrow it down further.

kern.ipc.nmbclusters=10000
was set in loader.conf.local, i changed the value to 1000000 per your post and the system didn't come back online. no ssh/ipsec/wan response. i have to go on site and change it back to 10000.

yaboc

after setting kern.ipc.nmbclusters=1000000 system never booted up it was hanging at
run_interrupt_driven_hooks: still waiting after 60 seconds for xpt_action

i tried to set the variable back to 10000 preboot and it was still doing the same. decided to intall 2.3.0 fresh and restore the config. so far so good. i'll repost if the issue continues.

yaboc

fresh install of 2.3 and restore the config with only pfblocker and siprox still does the same thing. LAN loses internet and reboot helps until the next time it happens. i'm going to switch back to 2.2.4 which was the rev i started this upgrade with.

Same problem here. After a few hours, on multiple devices, all with same nic+cpu.

Oh, and ifconfig em1 down and then up does help!

If you need anything else (tcpdumps, other stuff, etc..) let me know.

Hi all, back with another update after a BIOS upgrade and a complete fresh install, but the problem remains.

I didn't see it yesterday but there are errors in the dhcp log:

Apr 22 08:53:50	dhcpd		dhcp.c:3763: Failed to send 300 byte long packet over em1 interface.
Apr 22 08:53:50	dhcpd		send_packet: No buffer space available
Apr 22 08:53:50	dhcpd		DHCPOFFER on 192.168.10.100 to 00:b5:6d:00:d8:09 (R9Z0F0V) via em1
Apr 22 08:53:50	dhcpd		DHCPDISCOVER from 00:b5:6d:00:d8:09 (R9Z0F0V) via em1

That does not seem good! Any suggestions on this?

Regards.

Could you download the status tgz file from status.php and get it to me? Email cmb at pfsense dot org or PM me here to arrange transfer.

Thanks, emailed it ;)

I too am having this same issue on every box I have upgraded to 2.3. I have to say I have been pulling my hair out thinking I was the only one till I came across this thread. I am using several different platforms but for the sake of uniformity and just trying to get to the heart of the problem, let's cover the machines I am using most.

Firebox X750e and Firebox X1250e
2gb RAM
4GB CF
pfSense 2.3 nano embedded
LAN plugged into port 1 (sk0) of internal 4 ports
WAN plugged into port 1 (msk0) of 4 port expansion card
Firmware is upgraded and patched for serial port console during/after boot.

Symptom: The LAN connection goes out to lunch arbitrarily. I can unplug the cable and plug it back in and the LAN port is active again. Ultimately, it will go out to lunch again. The connection and activity lights will go out typically when this is happening but not all the time. When plugging the cable back in the lights come back every time if they were off.

I figured it was an issue with plugins however I have reluctantly uninstalled all plugins however the issue persists.

We were experiencing this issue with the WAN port as well but we did the disable of the hw.msk.msi_disable=1 and the WAN ports have not dropped out since. Granted, it's just been a few days so far… knock on wood.

I am going to move the LAN port over to an extra expansion port and see if there is a difference there. Will report back.

Let me know if there is any additional information that may assist in this troubleshooting process.

Thanks

we switched back to 2.2.x but it seems that

https://forum.pfsense.org/index.php?topic=110710.30

could be also a reason but i haven't' tried the workaround which is to only run it on 1 core. i'll wait for out of the box solution since these are production systems.

Thanks

So after moving the LAN port over to the expansion card of the firebox we have not had a drop out on the LAN yet. In addition, since doing the hw.msk.msi_disable=1 the WAN port still has not dropped out. Any reason we should suspect the on board 4 port ethernet interface drivers as the culprit here?

I'm also going to upgrade an existing vmware ESXi 5.1 box where I have pfsense running as a virtual firewall and see what happens there.
