Coda File System

Client Cache Files Limit

I have setup Coda 5.3.14 running on two servers in replicated mode, which is
working fine. The problem I have is when I try to write more files to the
volume than the client cache has cache files in table.

If I setup the client with a 20MB cache, venus reports that it initially has
handles for 833 files. Does this mean that if I write more than 833 files,
venus will lock up.

What I am doing, is using rsync to synchronise a directory with a directory
within the coda fs, and it would seem that venus dies at around the 833 file
mark. I get error messages:-

Is this by design?

This would mean that if I want to update 100,000 files, I need start venus
with a 2.4GB cache.
