Discussion in enlightened irc channel (OFTC/#ck) gave possible clue
for solving this, although it's just a quess:
0006 @ con || KordeX >4GB file?
0007 + KordeX || not all of those are
0007 + KordeX || i mean most of them are <100MB
0007 @ con | yes but that's the reason it failed
0008 @ con | rsync uses the rzip algorithm which was 32bit limited as I
discovered whenI was updating lrzip
0012 + KordeX || con > it uses rzip even when not using any --compress?
0012 + KordeX || or does it use it when using append-verify or fuzzy options?
0012 @ con | I'm not sure but it uses the rzip for the diff function I
think
0013 + KordeX || oh that's the reason i was affected
0013 + KordeX || i think i should re: re: my email with that update
0013 @ con | actually I'm guessing
0014 + KordeX || well i add this anyways, give one clue to them
0014 @ con | dont quote me on that, but I had all sorts of troubles
dealing with > 2^32 sized files with the rzip code
0014 @ con | and I had to rewrite most of the rzip algorithm to be 64bit
smart
0014 @ con | which unfortunately also slowed it down quite a lot
0015 @ con | unless you were working on >4GB files that is, where it sped
it up
Thanks to Con Kolivas.
