Calcru: runtime went backwards from 345 usec to 174 usec [solved]



  • I know this has been discussed before but I'm wondering what the latest news is on the cause and solution for these errors that I still get in 2.2.  Is someone working on an official fix?

    These errors happened on a clean install, though I did restore my old config.



  • Complete guess, but if you look at the time differences, you'll see them changing about 50%. Sounds like NTP syncing system time.



  • Why is this being logged though?  Shouldn't the NTP sync be automatic and silent?  It's not a big deal but these messages fill up my screen sometimes.  Do you get these messages on your pfSense?



  • @piz0t:

    Do you get these messages on your pfSense?

    Yes, but i can handle it.



  • Ok, if it's normal and not a bug, I'll mark this thread as solved.  Thanks for the answers.
