Hi Christian,

We are making use of the app's, the problem comes when we try to
upload a picture to the WebDav
the server freezes up. And we dont get logging output. We are running
virtuoso en a EC2,

[root@domU-12-31-39-03-CE-51 virtuoso]# df
S.ficheros         Bloques de 1K   Usado    Dispon Uso% Montado en
/dev/sda1             10321208   1818728   7978192  19% /
/dev/sda2            153899044    462344 145619076   1% /mnt
none                    873880         0    873880   0% /dev/shm

the problem does not show up with a pdf, or a .txt

We have found a problem in the image_magick plugin code (im.so) when linked with the Image Magick 6.3.8 (or newer) library as shipped with the version of Linux that our EC2 build is based on.

We are currently in the process of identifying what has changed in this version of the library that would cause this problem.

In case you do not require your WebDav to retrieve meta information from images, you can temporarily disable this im.so plugin by editing your virtuoso.ini and putting a semi-colon in front of the load line like this:

        [Plugin]
        ...
        ;Load4    = plain, im

You need to restart the virtuoso database in order for this change to take effect.

I will advice as soon as the EC2 image has been fixed with a new version.

Patrick
