I have updated two CWM instances with the latest version 0.9.9.5 and (re-)activated the cron-jobs to produce cached statistics every day/night.
For one cwm instance the jobs fail with an unspecified ERROR in ../application/jobs/log/<logfile>.
In the application log (../application/log/logfile) there is another error indicating duplicate objects in one model.
Possibly this is causing the cron based statistics to fail during model export?
However manual creation of the statistics (non-cached) in CWM is working for that model.
So maybe the problem it s the interaction between generator and cron script ?
please provide a log of the error in available
