very odd log entries (sysctl)

[Charles Sprickman]

Hi all,

Had a machine lock up recently.  When I got into it, I found that 
/var/log/messages and the dmesg buffer were filled with stuff like this:

Dec  1 18:17:14 h19 /kernel: 8 sendspace RW *Handler Int
Dec  1 18:17:14 h19 /kernel: 9 recvspace RW *Handler Int
Dec  1 18:17:14 h19 /kernel: 10 keepinit RW *Handler Int
Dec  1 18:17:14 h19 /kernel: 11 pcblist R  *Handler
Dec  1 18:17:14 h19 /kernel: 12 delacktime RW *Handler Int
Dec  1 18:17:14 h19 /kernel: 100 log_in_vain RW *Handler Int
Dec  1 18:17:14 h19 /kernel: 101 blackhole RW *Handler Int
Dec  1 18:17:14 h19 /kernel: 102 delayed_ack RW *Handler Int
Dec  1 18:17:14 h19 /kernel: 103 insecure_rst RW *Handler Int
Dec  1 18:17:14 h19 /kernel: 104 reass RW Node
Dec  1 18:17:14 h19 /kernel: 100 maxsegments R  *Handler Int
Dec  1 18:17:15 h19 /kernel: 101 cursegments R  *Handler Int
Dec  1 18:17:15 h19 /kernel: 102 overflows R  *Handler Int

Those seem to correspond to sysctl variables.

Any idea why the kernel would start spitting out sysctl mibs to the log?

Thanks,

Charles
