Hi all
The issue is that the "java.io.tmpdir" directory runs out of hard-disk space.
Magnolia continiously creates files in this directory named apache-tika-*. Although these files are later on marked for deletion, they never get deleted since active file-handles of Magnolia still exist to these files.
Output of "ls /srv/www/vhosts/delizio/catalina_base/public/temp":
no files, empty directory
Output of "lsof /srv/www/vhosts/delizio/catalina_base/public/temp" to identify open files:

After a few hours there is about 500 apache-tika-* files and each file has the exact same size of 22.5MB (23114 KB). On shutdown of Magnolia the file-handles are getting inactive, the deletion of apache-tika-* files is executed and the hard-disk space is freed up.
Currently I think it might be related to Lucene trying to index some ZIP files in documents workspace which are causing these troubles. Therefore I deleted the ZIP files and I'm currently waiting for customer feedback if new apache-tika-* files are still created.
Our Jackrabbit configuration is attached.
