I should have mentioned, this was with:
Aug 17 22:10:55 condor kernel: Linux version 2.2.11 ([EMAIL PROTECTED]) (gcc version
egcs-2.90.29 980515 (egcs-1.0.3 release)) #1 Wed Aug 11 12:09:06 BST 1999
The looping started at Aug 18 18:10:49 and looped once every 30s.
And, just after I'd sent the message it did something different:

Aug 18 20:12:35 condor kernel: 3: (03:06 0 1294374 2 2)
then more of what it did to start, followed by:
