I?m a novice at freeBSD, and that?s looks like an
error..what may be causing this?how to solve?
That's calcru: negative time -- an error message that
(unfortunately) shows up for any number of reasons.
Often the cause is buggy hardware, but sometimes it can be a software
problem.
For example there's:
http://groups.google.co.uk/groups?hl=enlr=ie=UTF-8oe=UTF-8safe=offthreadm=fa.g80oftc.186qv3o%40ifi.uio.nornum=7prev=/groups%3Fq%3Dcalcru%2Bnegative%2Btime%26hl%3Den%26lr%3D%26ie%3DUTF-8%26oe%3DUTF-8%26safe%3Doff%26sa%3DN%26scoring%3Dd
However, unless you're doing some sort of specific action that
triggers that particular case, that is unlikely to be the root cause
of what you're seeing.
See microtime(9) for an explanation of where this comes from. The
solution given there, ie:
# sysctl -w kern.timecounter.method=1
is a good thing to try first.
Cheers,
Matthew
