ReadyNAS 2120 Still crashes after 6.8.1 update

Question

Hello all,
&nbsp;
Here's the issue I have. We bought a ReadyNAS 2120 in 2016. It has been running well, but it start crashes since this month. i do update the firmware to 6.8.1 in last week, but it didn't fix the issue.
&nbsp;
Here's what happens when the crash occurs. The NAS stops responding to ping requests, you cannot ssh into it and the web interface is not accessible. Currently, we cannot gracefully reboot it, it has to be shut off via the power button on the back.
&nbsp;
There are no Apps running on the NAS, it has a few shared folders and just one NIC card.
&nbsp;
Do you guys have any idea what could be causing this, or do you have any advise on what else I could do to try and troubleshoot the issue?

So you use the NAS as a basic file server?
&nbsp;
Have you checked the diagnostics log in RAIDar for errors?
&nbsp;
Have you reviewed systemd-journal.log (or using ssh the output of # journalctl -a) from around when the crashes took place? Hopefully there would be some clues there as to why this is happening.
&nbsp;
We do have newer firmware&nbsp;ReadyNAS OS 6.9.0 now available!

No we use it for Backup. it will crash the system in the middle time during backup
&nbsp;
there are no log for errors that show in the admin page.
&nbsp;
the attach is the systemd-journal log that from around the crashes time.
&nbsp;
It looks like is&nbsp;out of&nbsp;memory problem.

Please don't tag the model as the RND2120. That's the ReadyNAS Duo, a 2-bay desktop device, and a very different product to your RN2120.
&nbsp;
OOM errors suggest a memory leak of some kind.
&nbsp;
You're looking for what it looked like right at the first OOM after the previous reboot to see where the problem started. kernel.log can go back further than systemd-journal.log. The journalctl command may go back further still.
&nbsp;
Do you have quotas enabled on the volume? If so, you could try disabling those.
&nbsp;
Which firmware did you update to 6.8.1 from (initrd.log will tell you)?

Sorry that for the wrong tag, since i am not a experience&nbsp;for it.&nbsp;as Check on the Kernel log, it seems there are nothing too much can see. form my guessing, the NAS should be running backup and cause lack of memory.&nbsp;the quotas did disabled already on the volume.&nbsp;But the NAS is update from 6.5.1 to 6.8.1.&nbsp;it seems not a good update right? anything i can do for fall back the firmware update and update it step by step?&nbsp;thanks

You shouldn't downgrade to older firmware than 6.8.0 after upgrading to 6.8.1.You could update to 6.9.0 (however you shouldn't downgrade from that firmware to older firmware).
