The following reply was made to PR kern/53350; it has been noted by GNATS. From: "Brian K.

It never fails at exactly the same place, but always within a minute or two and it never gets anywhere close to filling up the md-disk. In my case I was creating the 768 meg malloc disc and trying to copy /usr/src into it. initially I tried a couple times with midnight commander, and after that crashed twice, I tried just using tar mdconfig -a -t malloc -s 768m newfs -U /dev/md0 mount /dev/md0 /md0 cd /usr/src ;tar cvf - * |(cd /md0 ;tar xvf - ) /usr/src is only about 350 megs so it should fit easy, but just in case some difference in block sizes cause the same data to take up mor room on md0 than it does on the hard drive, I watched df in another console while it was copying. repeatedly looking at df in another consle showed the disk only reaching about 25% full at the time of kernel panic. I got some different messages each time one time I just got this line repeated scrolling up the console untill I decided to power off: initiate_write_filepage: already started the last time I got this: panic: kmem_malloc(4096) kmem_map too small: 275251200 total allocated syncing disks, buffers remaining... 7095 panic: initiate_write_inodeblock_ufs2: already started This is the 5.1 that is on the 5.1 iso as of about Nov/03/2003 Brian K.
