Sort of mea culpa, for which I apologise. In spite of my assertion (which I should have checked and didn't), the mount options differed. The working machines all specified rsize=8192. My box was using a much larger figure, of 131072 (ie 32 * 4096). It seems anything over 8192 causes this issue - that filenames get truncated. Whether that's a linux client issue or a freebsd server issue, or the result of interworking, I've no idea. Nor can I imagine why it should happen without errors being flagged up somewhere (I checked the logs at both ends) -- which is nasty, because I had a system that met the specs and mostly worked but very occasionally (< about 1 in 100k times, I reckon) failed silently. Ouch. Anyway, thanks to all for comments and advice offered. I'm back 'on the road'; maybe if someone else hits the same issue they'll find this thread. -- Mike Scott Harlow, England
