>Description:
I got a panic in ndp. I have a configured crashdump device:
# grep dump /etc/rc.conf
dumpdev="AUTO"
# ls -l /dev/dump*
lrwxr-xr-x 1 root wheel 12 17 сен 19:48 /dev/dumpdev -> /dev/aacd0p2
I have enough space:
# grep -i memory /var/run/dmesg.boot
real memory = 4294967296 (4096 MB)
avail memory = 4089982976 (3900 MB)
# swapinfo
Device 1K-blocks Used Avail Capacity
/dev/aacd0p2 8388608 0 8388608 0%
Each time FreeBSd panics and tries to do a dump, it panics again:
