psmintr out of sync <-- Whoa wazzat? HELP

[keith at smmc.qld.edu.au]

Hi all,
I have a problem or 2 (some personal some FBSD!)
I have a squid proxy machine FBSD 4.7 set up.
It has suddenly started reporting endlessly.....
(date stuff) proxy /kernel: psmintr: out of sync (00e8 != 0008)
(date stuff) proxy /kernel: psmintr: out of sync (0028 != 0008)

Any ideas how to fix it or what might be the cause??
Thanks in advance
