Description tschweikle 2020-05-30 10:09:36 UTC
Seeing this on two systems, both arm. Both where installed with 13.0-CURRENT, one downgraded to 12.1-STABLE

# uname -a
FreeBSD nc400 13.0-CURRENT FreeBSD 13.0-CURRENT r347896 GENERIC  arm
FreeBSD nc401 12.1-STABLE FreeBSD 12.1-STABLE r361362 GENERIC  arm

I wanted to install them both with current 12.1-STABLE and checked out sources to compile them on arm (Raspberry Pi 3b). Both failed with the very same error. A swapfile on an NFS-Volume was activated and got used.

# cat /etc/fstab
# Custom /etc/fstab for FreeBSD embedded images
/dev/ufs/rootfs   /       ufs     rw      1       1
/dev/msdosfs/MSDOSBOOT /boot/msdos msdosfs rw,noatime 0 0
tmpfs /tmp tmpfs rw,mode=1777,size=50m 0 0
nc158:/data/tftp /mnt nfs rw 0 0
md99 none swap sw,file=/mnt/swapfile,late 0 0

top reported swap usage after the compiler crashed:
# top

Swap: 2048M Total, 40M Used, 2008M Free, 1% Inuse

The sources where checked out at:
