well, in general your structure may be impossible to copy to Coda.
Coda max directory size is for the moment 256K and it is very probable
that your 14,069 files in two directories will overflow the limit
on at least one of the directories.

On the other side, Venus should not die in that situation, but return
ENOSPC. In your case it dies, apparently.

I see that you allocated a huge cache, with default RVM size calculation,
which most probably exceeded 1G - which very efficiently kills venus.

What did venus say at startup about RVM size?

You may want to either choose a smaller cache or, better, explicitely specify
the max number of files and hoard entries in the cache.
