Thank You to the suggestoins made to the syslog problem. After looking a second time,,I noticed this time in the syslog it was showing something about" kernel/boot was a binary files".( one line of logging)
I done a "Clear log" as suggested.
This got rid of 'the binary file ' thing',,and system log is working again now.
This machine actually panic rebooted ,again last night ,overnight,,,drove to the remote location where this pfSense machine resides to find one of the case cooling fans had quit and the second case fan is barley turning so,,I'm sure it is overheating,,,not an pfSense/OS problem at all.
Take Care,
Barry
