Sometimes i can't access to my banana thru ssh and etc. Link led is blinking. It happens everytime in HH:16:00 with random hour.

In syslog i get this messages:

i don't understand what is this...

Everytime syslog messages are same

armbianmonitor -u

and a description of what is your system doing. Then we could perhaps get to the bottom of the problem. Since we have a good modern kernel for A20 boards, you might want to try that first.

system works like NAS (smb, transmission)

i confused, because problem everytime comes in ~(random)hour : 16 min

modern kernel is https://dl.armbian.com/bananapipro/Ubuntu_xenial_next.7z.torrent ?

Yes. 

There are no suspicious in system logs. If a crash is initiated xx:16 check cron jobs (which are also not suspicious on first look), logs, ... Something must be running and that something should be checked what it does. Those boards usually run fine, even with this old kernel. I used one A20 machine for years, also for hosting this forum and I had no problems. The same board was also used for torrent downloading.

Which crash? According to the provided log the system has been rebooted on 'Thu Sep 28 15:17:14 MSK 2017' and is running fine. If you want to follow this 'issue' I would better try to clarify what the 'issue' could be...

 

Maybe suspicious: Ethernet connection is 100 MBits/sec.

I attach grafana screenshot with cpu and disk monitoring.

How we can see, in 16m graphics goes up.

system was freezed at ~ 18:17:12
I think, may be rsyslog doing somethink wrong...
Some peoples had same issue when rsyslog try to send log via tcp, but i not configure that.

What the heck are talking about? A system that freezes or crashes has to be powercycled afterwards. This obviously is not happening here, isn't it?

 

Do you refer to your Banana not being reactive any more every hour at a specific minute but then shortly after everything is fine again? If so and you use slow storage that can be caused by any heavy IO activity (especially random IO). You have 64.76 IO transactions per second on /dev/sda2 ON AVERAGE SINCE LAST BOOT, something's constantly hammering your disk. Just stop this and you're done (use iostat, iotop or every other tool that is appropriate to nail down such 'problems' on Linux)

For a long time, I suspected CRON to crash my Bananapi M1. But the fact is that CRON has a lot improved since I changed my PSU ...

 

As a matter of fact, by me the problem is not even the PSU but the contacts in the connectors. (And not only micro-USB).
