And stable ? > Can you try to remove nullfs from the set up ? Yes, I am using nullfs for the exports (mounting the exported directories to subdirectories of /srv). In the FreeBSD man pages and the documentation, the V4 export line in /etc/exports is often set to /, but as I come from Linux where /etc/exports looks completely different, I just followed my habits. As I wrote this, I executed the critical operation. It's finished and the FreeBSD server still runs *yay* :) So it's quite likely that the problem stems from the nullfs mount. I just remember an issue I already wanted to tell: Before the server crashed, the nfsd process ('nfsd: server') used 100% CPU (one core), but without progress on client side. Usually, the nfsd uses only up to 10% cpu time when rsyncing (values taken from htop - 100% = one used CPU). ...aaand I just run it once more, and it worked again :) --Norbert
