As part of this project I would like to add a field to the mbuf header to store some information. I have added the field, however I get an occasional core when trying to free an mbuf. It appears that the next field is getting overwritten with some garbage and a free, etc that tries to access this field is coring. I noticed that in FreeBSD 4.X this some fields were added to the mbuf header. I was hoping someone would be able to point me in the direction of the files/functions I should look at to solve my problem. - Chris To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
