Problem
After upgrading to OX 7.10.4, documents-collaboration can’t open documents. The error shows up in the fact that a timeout occurs at some point during opening with the error message “The document appears to be too large”.
Solution
With version 7.10.4, OX changed it’s documents-collaboration-setup. Now it is running a separate DCS-Daemon for high availability and/or large setups with multiple documents-servers.
For that, for example the apache2-configuration changed and a reverse-proxy-configuration for accessing the DCS-daemon was added:
root@example:/etc/apache2/sites-enabled# cat ox.conf
[...]
RewriteRule (.*) http://localhost:8009/servlet/dav$1 [P]
[...]
It is recommended to go through the OX manual for the DCS and check if all configurations have been made and all databases, passwords and files are present.
