Description Need Real Name 2002-06-29 10:12:53 UTC

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:0.9.4)
Gecko/20011128 Netscape6/6.2.1

Description of problem:
I have ntpd running, and every 2 or 3 days, the computer stops responding: no
shell, no keyboard, no mouse, no remote ssh, only responds to pings.

Version-Release number of selected component (if applicable):ntp-4.1.1-1


How reproducible:
Always

Steps to Reproduce:
1.My /etc/ntp.conf file is:
server time.nist.gov
server 127.127.1.0
fudge  127.127.1.0 stratum 10
driftfile /etc/ntp/drift
authenticate no	

Actual Results:  Server hangs after a couple of days. Apparently no error log in
/var/log. But no response fom keyboard, mouse, remote console, or vnc.
It still responds to ping.

Expected Results:  nothing

Additional info:

Comment 1 Harald Hoyer 2002-07-07 10:06:43 UTC

this does not seem to be a ntpd problem... normally the kernel you use hangs in
this case... reassigning to kernel

Comment 2 Arjan van de Ven 2002-07-07 10:12:03 UTC

This sounds like something oopsed.... any chance of getting the oops output?
