We saw something very similar to this about a year using FFS and soft updates when we were building a NAS appliance. The details escape me and I no longer work the company so I cannot grep the source code but here's what I remember. The softupdate code periodically flushes the meta data. There is a flag in the soft update code that periodically sets a flag to starts the meta data flush timer. There was a condition in which this flag was not set properly causing FFS to freeze, in particular with NFS running. Hope this helps.
