WAN Interface Keeps Going Down

[jamesosw]

Hi,

I'd been experiencing my OPNSense WAN interface keeps going offline without any reason.

The first error retrieved from the System Log as follow:
2022-08-01T10:43:59   Error   opnsense   /interfaces.php: ROUTING: entering configure using 'wan'   
            Pe��^ݤfH16~`��;��w��ܪL��2%��VL{E�����ׄ�����"M$=��

��������3���Ezdi��!   
            <13>1 2022-08-01T10:43:01+08:00 Gatekeeper.uniqcs.local ����|���n

I plan to run an upgrade to 22.7 later this week but appreciate if anyone could provide some guidance to this weird encounter.

Thank you.

Still no success.

Could memory be a constraint? Running 6GB with a few plugins
