kerneloops eating up cpu

After googling I found this to be a common problem
when some error message is flooding /var/log/messages.

Apparently it is ok to  killall kerneloops;
I did,
and this does of course stop it from eating cpu.

But it doesn't solve the basic problem, what is flooding the messages file?
In my case it is huge number of lines:

Any advice on this?
Might it be tied to my somewhat frequent X-freezes?

As it stands now I will still continue to get the large messages file
requiring me to truncate the file, every day or so
