sgjava 76 Posted June 6 Share Posted June 6 Armbianmonitor: http://ix.io/3oWZ Howdy, I'm running Armbian_21.05.1_Odroidxu4_focal_current_5.4.116.img on my XU4 for security cameras. It averages about 60 Mbps 24/7. After a couple days usually one adapter disappears (from ip a and nmtui) and sometimes both (I have a USB 1 Gbps adapter too). I'm not seeing anything in the logs to indicate an error. I monitor this system with Zabbix and I see no unusual activity before this happens. Is there a way to get diagnostics for this event? 0 Quote Link to post Share on other sites
lanefu 329 Posted June 7 Share Posted June 7 probably follow dmesg -w -T from serial console or tee into log file 0 Quote Link to post Share on other sites

lanefu 329 Posted Monday at 08:52 PM Share Posted Monday at 08:52 PM Lol id be looking for less page allocation errors. Hard to tell. Is memory consumption tight? 0 Quote Link to post Share on other sites
sgjava 76 Posted Monday at 10:34 PM Author Share Posted Monday at 10:34 PM Yeah, looks like https://github.com/aler9/rtsp-simple-server might have some issues, but that shouldn't kill the NICs. Memory averages around 1.3G free which is excellent for 5 4K cameras. Nothing obvious sticks out. I have a SSD and 1G Ethernet dongle connected to USB 3. I believe I have a 4A power supply. I have another XU4 with 2 SSDs on USB 3 that works fine, but has less network activity (like 20 Mbps). The weird thing is the heartbeat is till cranking and I have to power cycle to get NICs back. If it makes any difference I have 5 to 7 ffmpeg processes running all the time. Processes average around 150. I didn't tweak any kernel parameters. Anyways, I tried swapping power supplies with another board just for the heck of it. 0 Quote Link to post Share on other sites
lanefu 329 Posted Tuesday at 12:59 PM Share Posted Tuesday at 12:59 PM so I did see interrupt stuff regarding the NIC. I don't know exactly what it means.. but look here for inspiration on knobs to turn https://github.com/armbian/build/blob/master/packages/bsp/common/usr/lib/armbian/armbian-hardware-optimization#L145 0 Quote Link to post Share on other sites
sgjava 76 Posted Tuesday at 01:54 PM Author Share Posted Tuesday at 01:54 PM 6A PSU https://www.hardkernel.com/shop/5v-6a-power-supply-unit/ When you connect an external 2.5inch HDD/SSD to XU4 or using the CloudShell, the bundle 5V/4A power supply is not enough to supply stable power. We strongly recommend to use this 5V/6A PSU to improve the system stability. So maybe my PSU theory is correct. Would also explain where there's really nothing in the logs. Just ordered this guy. No use troubleshooting a software problem until I rule out hardware https://www.amazon.com/gp/product/B07H9X8FHM 0 Quote Link to post Share on other sites
lanefu 329 Posted Thursday at 01:29 AM Share Posted Thursday at 01:29 AM Haha yeah that should cover it! 0 Quote Link to post Share on other sites
sgjava 76 Posted Friday at 01:08 PM Author Share Posted Friday at 01:08 PM I'll report back once I see the issue resolved. I think a couple days was the maximum time without losing the NICs. 1 Quote Link to post Share on other sites
