Cron task ScanFiles takes hours to finish

Is clearing the oc_jobs a solution for the problem or does it create more problems - like mentioned as a solution in this thread

Background jobs never end, high cpu mysql, after update 17.0.3 -> 18.0.1

SOLVED! Okay, I finally figured that in the oc_jobs table there could be a (long) list of scheduled jobs. (From the logs it seemed that mysql was just constantly selecting new jobs) And indeed: > 250000 jobs of the ‘maps’ app. Just emptied the whole table, everything is fine again. NB: note that this also deletes all regular cron jobs. Update to a new (minor or major) version, or reinstall solves that.
