Hello,
Are you using some versión of Activiti BPM (https://www.activiti.org/) software ?
If this is the case this forum its not the correct place to make your question. Although APS and Activiti share the same origin, they are not the same product.
In any case, reading your log messages is seems that you have somo I/O problem in your instalation. Check if your app have permission to write on disk.
Regards
