Vroom Posted July 3, 2015 Posted July 3, 2015 This is feedback on my experience upgrading to 4.0. After upgrading, my apache is dying at least 5 times a day, causing all sites on the server to be unreachable. I never had this even once in the last 5 years. Forum has 2 million posts with 30,000 page views per day, which is not that much for a very powerful dedicated server with only a few other less active sites on it.
Vroom Posted July 3, 2015 Author Posted July 3, 2015 Disabling the one minute cron dropped the load down, though still slightly higher than before. I will watch it today and see if the apache problems come back or not.
Daniel F Posted July 3, 2015 Posted July 3, 2015 Are the background processes still running or have they finished?If they're still running, I would suggest to activate the cron feature ( ACP => System => Advanced Configuration ) which will speed this up
Vroom Posted July 3, 2015 Author Posted July 3, 2015 The background processes were still running. I had already activated the cron setting.It looks like the crons were what killed my server. I will test it without the crons running for a day.So far load is looking very normal now that the cron was disabled. But I will have to get the background processes completed slowly without over burdening the server, maybe with a bigger time gap, or maybe manually.
