Dear all,

I am using Calibre latest version (1.0.0) on Linux 64 bit. I have a 4k big library and trying to add more books. I add the books by "one book per sub-directory", as I am adding them from another calibre library copy (so there are metadata.opf files for each book).

When adding larger numbers (100 and more), I quite often get the problem that a significant number (30-50%) of the books are inserted without any metadata and author and title are both set to "Unknown". The accompanying error message is e.g.

Code:

Wuthering Heights - Emily Jane Bronte.mobi
Traceback (most recent call last):
  File "site-packages/calibre/gui2/add.py", line 171, in add
  File "site-packages/calibre/ebooks/metadata/opf2.py", line 547, in __init__
IOError: [Errno 2] No such file or directory: u'/tmp/calibre_1.0.0_tmp_iOXa_c/lk_Gat_rm_worker/97.opf'

Based on another post, I checked that I have sufficient memory and storage. However I have 8 GB of RAM (with half unused) and several GB of storage in / (where /tmp and /var both reside).

Adding any of the affected books again (even in bulk) works fine. So it's not the books. I also notice that the books that fail to import properly are usually - when sorted alphabetically - at the beginning of the import list.

P.S.: Import is also terribly slow. It takes many minutes to add one 100 books. I've minimized the tag view and the book detail view.
