perfSONAR User Q&A and Other Discussion

[Zhi-Wei Lu <>]

Hi all,

 

On one of our perfsonar boxes, the owampd keeps dying.  I got error messages initially, when I try to start it:

 

owampd[4923]: FILE=time.c, LINE=112, NTP: Status UNSYNC (clock offset issues likely)

owampd[4923]: FILE=time.c, LINE=118, NTP: STA_NANO should be set. Make sure ntpd is running, and your NTP configuration is good.

/etc/init.d/owampd start: owampd started

 

Owampd would die right away.  The ntp is running on the server:

Do I have to wait for bit until the ntp is “stable”?  I just rebooted the server a short while ago (actually, I swapped the identities of two perfsonar boxes this morning).

 

I would appreciate ideas to correct the issue here.  Thank you.
