I tried 60 seconds for timeout but that didn't work. I guess Ill double it now and keep trying.
I have about 260,000 pending jobs, and nothing is getting done. I know what you mean about purgeOldjobs. That service is crashed now and I deleted old jobs from the database by hand. I was up to 2.6 million rows. Ofbiz was pretty much unusable. If you have any other suggestions I'd love Yo hear them.
