--- Comment #15 from Martin Steigerwald <ms at teamix.de> ---
Daniel, a NetApp expert co-worker confirmed that your assumption that the error
code refers to the directory is correct:

Wed Mar 26 09:12:13 CET [somevfiler at somefiler:wafl.dir.size.max:warning]:
Directory /vol/nas_user_home/ms/.local/share/akonadi/file_db_data/ reached the
maxdirsize limit. 

My co-worker raised the limit, yet still, I think its wise to split 280000
files into several sub directories. There may be other storage system or
filesystems that may have a limit there. And even if not: I bet the lookup time
of a directory increases with amount of files in it.

I renamed the bug report and set it to wishlist as its technical not really a
bug.
