Hi Torren,
Did you try checking above SAP note ?
I requested you to ping with hostname, don't use IP address, for hostname to ip resolution.
Execute sappfpar pf= <full path/instance profiles> check
Now, If you have already done the kernel update or revert back the changes you have done on your system before the problem started, I would like to see dev_ms logs for the same.
Regards,
Divyanshu
