Server randomly unreachable after 6.12.1 update

[SMLLR]

Hello,

I recently updated from 6.11.5 to 6.12.1 and have been experiencing some stability issues. So far the server has become unreachable twice in the last few days, leaving me to force shutdown the server. The server loses all network connectivity so, since I am running this headless, leaves me with no way to interact with the server. I plan on connecting a monitor, but I have to have one connected at power on for it to work for some reason, so I have yet to do that.

 

I did, however, enable mirroring syslog to flash drive. Unfortunately, this did not seem to shed any light on the issue as the last entry in the syslog file prior to the reboot is a few hours prior to the issue. Though, looking at the syslog after the reboot, one thing did stand out to me a bit, but not sure if it is related:

Quote

*** WARNING: Detected another IPv4 mDNS stack running on this host. This makes mDNS unreliable and is thus not recommended. ***

 

I have attached the diagnostics log that I pulled immediately after powering back on.

 

Thanks
