Truncated log entries

[Barry Roomberg]

I'm running Fedora Core 2 Kernel: 2.6.5-1.358
I'm logging activity in a directory (thanks Stephen).

I occasionally get what look like to be truncated log entries such as:

Oct 27 11:24:21 mstoppel1 kernel: audit(1098890661.257:8894633):
avc:  granted  { read } for  pid=17834 exed=500 fsuid=500 egid=500
sgid=500 fsgid=500

"exed=500" ???

also:
Oct 27 11:26:47 mstoppel1 kernel: =500 fsgid=500


Any idea why?  They are rare and interspersed with good entries.
