Hi everyone,

we are still having difficulties with digikam. It did re-index the whole
collection as I described some weeks ago. All database entries were set,
but I still had no digikam that showed up, only that nice splash screen
is "reading database". Having lousy network traffic of about 300 KiB/s
produced by dk I did a strace. It seems that there are a lot of timeouts
and it is searching and testing write access (?) thru the
sub-directories with the thumbnails produced by my NAS for each photo.
These files are owned by root and have chmod 777.

strace -p #:

It goes thru about 2000 files per hour. In one week it might be finished
with all of them.
I would like to understand, what dk is doing all the time.

Any clue or hint?

Thanks again.

Ben
