arp: writing to routing socket: Cannot allocate memory

[A Former User]

Hi guys,

I've got some strange behavior on pfSense (please see attached log) since last week. I'm not quite sure if I can tell you 100% how to reproduce that errors, because it happens even if there's no user-interaction on the network.

What's really strange is if I'm downloading something from PC (VLAN20) to my QNAP (LAN) - even if it's a simple picture, the whole network "breaks" and not a single device is ping-able. Only thing I can do is to HW-reboot my pfSense appliance.

pfSense:
2.5.0-DEVELOPMENT (amd64)
built on Sat Apr 25 20:47:08 EDT 2020
FreeBSD 12.0-RELEASE-p10

CPU-24h-avg is at 10.5%
RAM-24h-avg is at 15.26%

I'd be really happy if you could have a look into pfsense_mem.txt and give me some advice/ideas how to solve this.

Many thanks & KR!

PS: as you can see I'm not a professional, so please forgive me if I'm using the wrong terminology.

it looks like the network is going down, are you using the official realtek driver or the embedded one?
it can be a driver issue
https://redmine.pfsense.org/issues/9606

driver for 2.5.0 is here
https://drive.google.com/open?id=1IBhB9fRpE8IRWP8cK-xtDiHmMpQtit0c
extract the tar

Place "if_re.ko" file at "/boot/kernel"

Change ownership and permissions on the if_re.ko file

chown root:wheel if_re.ko
chmod 0555 if_re.ko

Then edit or create "/boot/loader.conf.local” and add this line:

if_re_load="YES"

Reboot.

Then go to diagnostics > command prompt in the WebGUI

Run the command

kldstat

If you did everything properly you’ll see "if_re.ko" in the list that comes up.

Hi @kiokoman,

first of all - many thanks for this!

I followed your step-by-step guide, one thing to mention;
if_re_load=“YES" - the “ is not a standard quote (&#34 ;), but a left quotation mark (&#8220 ;), causing the loader.conf.local to be not correctly loaded.

if_re_load="YES" will work as intended, and I get if_re.ko after entering the kldstat command.

Will keep you updated in a week or so!
