Hi *,
this seems to be the identical to bug #354087:
I had this "kernel bug" triggered two times. The process that seemed guilty was
Coldfusion 5.0, running as an wwwrun-type user.
Both machines are HP DL380 with Intel Xeons and 3 GB of RAM. I was not able to reproduce that bug directly, it just "appeared" once on the two servers.
Please feel free to contact me via email, if I can provide any other info that would be usefull for you.
Best regards,
Tom
