we have an urgent problem with our xwiki installation. It only shows blank pages.
I installed a velocity script that creates links to all pages underneath the root page (with a for loop) and builds a list from it. (Because the documentTree root option is not working for me)
I realized that the loading time of some sites was extended by the script.
Tonight the memory and CPU usage went to over 90% on the server (4 cores and 16GB memory - tomcat8/default -xmx=12g).
The problem is at the moment, that we cannot access any pages to delete the script/macro. Can you think of any fast solutions to access the sites without them loading correctly? Like a maintenance mode were velocity is deactivated?
I have some log files if you need them but I couldn’t find anything special (except for the normal Java issues) in there.
Greetings and thank you for help
