Wish I could be some help but I upgraded to 6.8.3 and the issue went away.

Hi All I have Unraid (6.8.2) on a Dell R710 and recently have been experiencing issues with complete loss of network connectivity that require a reboot to get working again. The times seem to vary between about a 1.5 days and a week or so with no obvious pattern. After the last time it happened (last weekend) I enabled logging syslog to the flash drive to preserve the logs (which I have attached). The lockup starts at line 1607, Oct 21 17:05.

Is it likely to be software or hardware? If any more information would be useful, I'm happy to provide it. Thanks in advance. syslog
