Hi all, I have a problem with my NAS. Lately, the system has been either nonresponsive or overloaded with CPU. When this happens, I am unable to access my shares or the web interface. When I check my logs, I find what appears to be part of a core dump. Also attached is a copy of the diag zip file. Where do I start to resolve this issue?

Macvlan call traces will usually end up crashing the server, switching to ipvlan should fix it (Settings -> Docker Settings -> Docker custom network type -> ipvlan (advanced view must be enabled, top right)), then reboot.

Thanks made the changes and will monitor the results

 

Thanks that solved the issue.
