I experienced a weird issue on saposcol. It stops suddenly without anyone stopped it. When I tried to re-run, the such error like cannot access dev_coll.tmp appear, I believe restarting the server will solve my problem (saposcol resource will be released).
Preventing this to happen in the future, the question is, what is the cause of saposcol stops suddenly ? I've tried to search on forum but finding a dead end solution.
