OpenVPN (UDP)
hAP AC3. Very similar problem (viewtopic.php?t=197690). But addresses and routes are present.

I confirm this problem exists!

hAP AC2

P.S. works in TCP mode

Regarding the OVPN service not working with 7.10. We have found the issue and will release 7.11beta with a potential fix soon. However, the issue is not a bug exactly. If you are running OVPN service with 7.10.2 and it is not working, check if you use OVPN in "IP" mode, but have specified...

After updating to 7.10.1 from 7.10, OpenVPN stopped working. Connection is established, but there is no traffic through tunnel. After downgraded to 7.10 and everything was OK. /interface ovpn-client add certificate=client_test.crt_0 cipher=aes256-cbc connect-to=xxx.xxx.xxx.xxx mac-address=02:4F:B6:A...

I updated to 7.8beta2. The memory leak continues.

After updating to 7.8 beta3, memory leak problem solved.

...
Also consider to upgrade one router to 7.8beta2 to see if it has been fixed there. It may be that late DNS fixes did not make it into the release.

I updated to 7.8beta2. The memory leak continues.

If you didn't try it, try rebooting the MK box after disabling "allow remote requests" just to "clean" everything up. If you already tried, maybe it's not DNS resolver related. I disabled DNS, reboot MT and problem was solved. /ip dns set allow-remote-requests=no cache-max-ttl=1...

... The resolver (DNS) daemon experienced some problems on the latest RCs before the v7.7, and it's really known to have been very changed from 7.6 to 7.7. ... I disabled "Allow Remote Requests" and configured provider's DNS server for clients. But the problem remained. In one hour, 1 MB ...

You keep saying there is "a problem", but still you have not provided any evidence of there being a problem at all. Has any of your router crashed any time, or otherwise had any performance problem, due to this "problem"? I have problem. My hap ac2 rebooted with error "out ...

No ... all boxes i'm running and presenting the memory behavior change from 7.6 to 7.7 were previously installed on v6 and upgraded to v7 (no problem at all), likely v7.3 or v7.4, and later upgraded to v7.7. ...

The situation is similar.

One question to @leonardogyn and @Ocean (maybe it was asked and answered before but I didn't see it)
Did you ever in the past netinstall your devices with ROS7 and clean config ?

I didn't use netinstall with ROS7

i have a pair of hap ac2 with 7.7 with a basic configuration and dont exibit this behavior, just basic router doing NAT and wifi, please give more details about your use case to see if its related to a specific feature I use: CAPsMAN (with one local AP); L2TP server - 8 clients EoIP - 1 OpenVPN UDP...

with this memory usage increase rate, you'll likely max out on less than 48h. And you'll either watch the box crash or nothing happens at all. The first option would strongly suggest some memory leak. The second one, would suggest memory usage behavior just changed DRASTICALLY from v7.6 to v7.7. To...

ROS 7.7
hAP ac2

Constantly linear increase in memory usage

Earlier in the logs, I saw messages that there was not enough memory and a reboot with a kernel error. Logs are not saved.

Now I'm monitoring the situation.

I tested ability to provide power via PoE to an Unifi AP AC Lite from CRS328
Works great both from 802.11af/at and passive!

llag, thanks for the info!

Soon I will test 802.3AF with AC lite and report the results.

Why dont you have a look at the specs ?
So, according its specs, Unifi ap ac lite uses as well Passive PoE (Pairs 4, 5+; 7, 8 Return)...
So i guess it will work...

I read the specs, but I am interested in real experience of operating Unifi ap ac lite with CRS328.

Mode B is used....
All MikroTik PSE uses the same PoE-Out pin polarity Mode B 4,5 (+) and 7,8 (-)
https://wiki.mikrotik.com/wiki/Manual:PoE-Out

Unifi AP AC Lite receives PoE power from CRS328? No problem?

Ok, I think I found the answer: the CRS328 uses mode B pins for POE, the Ubiquiti AP (AC-Lite and AC-LR) use for 802.3AF use mode A pins (only) but can be powered with passive POE 24V on mode B-pins. The CRS328 can power an AP using passive POE on mode B pins. Now I just need to find out how to con...

Wireless scanner reports some networks with /DP after the channel:
5280/20/an
5280/20/an/DP
what does it mean?

D - DFS (radar-detect)
P - Passive

If used in l2tp client "add-default-route=yes", then the routing table is not correctly created and VPN does not work (on ROS 39.3 everything ok). Example: ROS 6.40.8 l2tp client config: [admin@Dom-3G-Router] > /interface l2tp-client print Flags: X - disabled, R - running 0 R name="l2...

After the upgrade to version 6.40.1 from 6.39.2, problems with PoE ports: 00:10:11 poe-out,warning ether4 detected poe-out status: short_circuit 00:10:13 poe-out,info ether4 detected poe-out status: wait_for_load 00:10:14 poe-out,warning ether4 detected poe-out status: short_circuit 00:10:14 poe-out...

Exactly the same problem I have on 960PGS. RoS 6.40.1.
I returned to version 6.39.2 and everything is fine.
