>Description: Reproducible panic: FreeBSD panics after get full filesystem with a ufs snapshot. kernel and userland is standard, with no tweaks, only in /boot/loader.conf: geom_concat_load="YES" (the affected filesystem is gconcated of several partitions). In sysctl.conf, I have: kern.ipc.somaxconn=256 kern.maxfiles=25000 >How-To-Repeat: In a ufs filesystem with soft updates and some snapshot taken previously, do some heavy write activity. The snapshot will grow a lot; if that snapshot fill up the filesystem you will get a panic. Full backtrace in http://pastebin.com/MZP2Femp. This PR is pretty similar to kern/162362. >Fix: >Release-Note: >Audit-Trail: >Unformatted:
