It appears the server is not saving some wavelets correctly. When I
restart the server, sometimes an error like the following pops up:
[java] SEVERE: Error reading delta file for [WaveletName
nsb0.net/w+3FN4kqwu2UA/nsb0.net/conv+root] starting at 934908

And that wave then shows up as truncated.
This ... is a bit of a severe stability issue :P I have an archive of
the binary deltas I think caused the issue. (Can you send attachments
to a mailing list?)
Cheers!
