i should mention that through strace i saw a long series of writes to key_index.dat that were of under 10 bytes each.

sorry. also, that downloads were terminated in this condition, but uploads continued at all times. thus, with the problem i described, my U:D ratio would be much higher than i desired, 5:1 or more.

Did you have your temp files on the NAS too?
I don't know exactly how your network file system works, but there is at least one critical case: when a near-end part arrives and the temp file suddenly grows in size. If the grow happens by physical transfer of data to the file you will have a problem if it's on a network.

I'd prefer to have such issues discussed on the forum instead of here.

sturedman, yes, initially the temp files were on the NAS too. i accidentally launched it with local conf files and remote temp files, though, and that worked correctly, so i guess it had to do with access to the confs.

the problem you describe sounds like something that would happen sporadically, but this was a regular problem.
