Fragments of kernel log text in "security run" message

[Ralph Dratman]

Until recently, my "security run" messages from Release-4.7 have been 
reasonably comprehensible. Certain events and changes have been 
reported, such as login failures and setuid changes, but I could 
always figure out roughly what was being reported.

Recently, though, I've been seeing small fragments of text in the 
"kernel log" portion of that report. This happens almost every day 
now. Following are a few examples. There is just one fragment per 
report.
---------------------------------
kq9.net kernel log messages:
> copeid 0x4

kq9.net kernel log messages:
> 8>.

kq9.net kernel log messages:
> nal_number pid ...

kq9.net kernel log messages:
> rved.

kq9.net kernel log messages:
> 0/16/63] at ata0-slave WDMA2

kq9.net kernel log messages:
> d to support NFS

kq9.net kernel log messages:
> /ad0s1a:

kq9.net kernel log messages:
> , 4950 blocks, 2.0% fragmentation)

kq9.net kernel log messages:
> TEM CLEAN; SKIPPING CHECKS
---------------------------------

Each of these messages looks like a valid fragment of a bootup 
message, but I don't see why I should suddenly be getting these in 
the security report.

Does anyone know where this stuff might be coming from?

Thank you very much.
