An issue may be my sys config, as /tmp and swap are memdisks. Not sure how or if I can modify fstab or the config to get swap on disk for a crash dump save since the disk has no swap or tmp partitions. From fstab: /dev/ufs/hd250G1root / ufs rw,noatime 1 1 /dev/ufs/hd250G1var /var ufs rw,noatime 2 2 /dev/ufs/hd250G1usr /usr ufs rw,noatime 7 3 tmpfs /tmp tmpfs rw,mode=01777 0 0 md99 none swap sw,file=/usr/swap/swap,late 0 0 # gpart show ada1 notes => 34 488397101 ada1 GPT (233G) 34 6 - free - (3.0K) 40 1024 1 freebsd-boot (512K) 1064 984 - free - (492K) 2048 8388608 2 freebsd-ufs (4.0G) (/root) 8390656 33554432 3 freebsd-ufs (16G) (/var) 41945088 446452047 4 freebsd-ufs (213G) (/usr) physical memory is 4G Thoughts on how to proceed?
