Both ReadyNAS Ultra 2 Plus NAS crash repeatedly

[Edmundcramp]

I have a pair of ReadyNAS Ultra 2 Plus boxes, each with 2x 1Tb drives mirroring each other and both running RAIDiator 4.2.22 - these both crash every couple of weeks:

I can provide the entire log if anyone has a clue why this is happening.

Can you provide more of that call trace error below?

I followed up on the line:

> Nov 13 01:38:11 scarlett chronyd[2592]: NTP packet received from unauthorised host 192.168.0.2 port 2048

This IP address is a wireless AP on the network that was not supposed to be running NTP - I went back into the setup on the AP and disabled the NTP access completely on the device and this seems (so far) to have cured the problem - no crashes in 12 days now.

However the local NAS logs are reporting that chronyd can't access 209.249.181.22 ...
