First thing I would check is the CMOS battery if you have one or can get to it. Sounds like system time is not being held. Go through boot log. If the system corrects shortly after a. Nts comes up and b. Network connection is established then this may be the case. Couple dollars for a button battery will have you right.

My F22 randomly crashes to a frozen state that requires a power cycle to restart.
When this happens, the time stamp on log files such as /var/log/messages changes for a while before reverting to the correct date and time.
Today,the sequence was:

Jul 24 10:55:55 mustang rsyslogd: [origin software="rsyslogd" swVersion="8.8.0" x-pid="853" x-info="http://www.rsyslog.com"] start
Jul 15 11:19:20 mustang systemd: Stopped target Default.
Jul 15 11:19:25 mustang systemd: Stopping Default.

followed by some 17,000 lines with Jul 15 through to:

Jul 15 19:28:11 mustang named[1221]: client 122.61.143.143#39431 (isc.org): query (cache) 'isc.org/ANY/IN' denied

Jul 24 11:06:11 mustang rsyslogd-2177: imjournal: 2971956 messages lost due to rate-limiting

A similar thing happens in /var/log/secure (though with fewer Jul 15 entries).

The Jul 15 dates have been appearing at/after the last two or three crashes.

Even though the Jul 15 entries look to span over eight hours, the actual time span was only a minute or so.

Any suggestions as to what is happening here?

Cheers and thanks,
Stephen
