Wired memory usage slowy increasing
-
Hi!
I've had a pfsense box running for a couple of months as our company's internet gateway and I absolutely love it! So powerful… anyway, the basics of the setup are as follows:
AMD Phenom II X2 225 CPU w. 4GB DDR3 on an Asus M4N689T-M board, with an APC UPS plugged in via USB. There are four NICs:
nfe0 which is our LAN on 192.168.0.0/16 (LAN1)
A multi-wan setup on rl0 and rl1 involving PPPoE connections to our two ADSL modems
em0 which is separate LAN on 10.0.0.0/24 (LAN2)I've installed the Apcupsd package, Snort and the OpenVPN export utility (though the VPN is currently disabled)
We have the usual traffic between our LAN and the multi-wan load balancing gateway. The separate LAN is not physically secure; as such I've used the firewall/NAT to drop any inbound traffic to our LAN but allow connections from LAN1 to LAN2. LAN2 traffic is very high as it contains the (network block device, encrypted) offsite backup server and an IP camera monitoring the room that it's in.
All was seemingly fine until a recently when after a power failure and subsequent reboot the wired memory usage grew and grew until swapping occurred; after having a tinker I restarted the box and it was fine for a week and now the same thing has happened again. It seems that devbuf's memory usage grows over a couple of days until we run out of memory - aargh!
I'm not too familiar with BSD, my day job is Linux - but to me this looks like some sort of memory leak. I've not yet filed a bug as I don't think I've got enough useful information yet - I've included things I thought may be useful in the post, hopefully someone can point me where to dig next!
One odd thing I noticed was that dmesg shows me some sort of USB error. I found an old post on tinterwebs showing a similar thing to do with a USB1 hob - could this be related?
The system is currently still up and running and in this funny state - I reckon I've got about a day before it needs restarting, so if anything else useful can be gleaned let me know!

I've installed the Apcupsd package …
All was seemingly fine until a recently when after a power failure and subsequent reboot the wired memory usage grew and grew until swapping occurred ...
One odd thing I noticed was that dmesg shows me some sort of USB error ...
recent dmesg output, repeated many times:
ugen0.2: <unknown> at usbus0 (disconnected) uhub_reattach_port: could not allocate new device uhub_reattach_port: giving up port reset - device vanished usb_alloc_device: set address 2 failed (USB_ERR_IOERROR, ignored) usbd_setup_device_desc: getting device descriptor at addr 2 failed, USB_ERR_IOERROR usbd_req_re_enumerate: addr=2, set address failed! (USB_ERR_IOERROR, ignored) usbd_setup_device_desc: getting device descriptor at addr 2 failed, USB_ERR_IOERROR usbd_req_re_enumerate: addr=2, set address failed! (USB_ERR_IOERROR, ignored) usbd_setup_device_desc: getting device descriptor at addr 2 failed, USB_ERR_IOERROR</unknown>Did the USB errors started showing up after the power outage?
At first glance I would try disconnecting USB from your UPS, and perhaps temporarily remove the apcpusd package. Maybe the power outage damaged the USB port on the UPS (how ironic!). It's not clear to me how that could cause a memory leak, but a lot is possible with damaged hardware.

Thanks charliem! I'm starting to think that USB is the root of the issue.
I fired up the apcupsd status panel and got the "could not connect to service" error; according to the system logs apcupsd was not started as the UPS could not be found. I unplugged the UPS, plugged it in again, checked dmesg and got the following:
ugen0.2: <unknown>at usbus0 (disconnected) uhub_reattach_port: could not allocate new device ugen0.2: <american power="" conversion="">at usbus0</american></unknown>I went into the apcupsd panel and hit "Save" on the configuration page then clicked over to the "Status" tab and lo and behold, the UPS service had been started and the status was printed out. This was a couple of hours ago; I've just checked the RRD graphs / vmstat and the wired memory has stopped increasing and leveled off, and no funny USB related stuff in dmesg either.
I've checked the UPS' USB port on my linux dev machine and all seems just fine, my guess is that there is an issue with the USB driver and the way it is initialising the USB hub which is hung off the controller on the motherboard. I've detached the UPS' USB for the time being, will restart it and see what happens. Incidentally I plan to upgrade the hardware to a more modern Haswell CPU / board in order to save some power so I'll do the same set of experiments once that's up and running in a couple of weeks.
Many thanks for your help! If things start to get wierd again I'll append this thread with an update as it does seem there may be an underlying issue with the kernel and this USB configuration.
