file corrupt

Check you’re NIC or switch “jiffies” errors are known with NIC issues.
If you have some file corruption go to the Console screen enter CTRL + ALT + X then select “Repair file system on LV” this will reboot system.
Also try using another NIC to test of error present again. Clear logs to get fresh logs as well.
