One of our ACP background tasks, sitemapgenerator, keeps occasionally locking and then running again. Some days it will run fine without issue, but then it will lock suddenly and stop running at certain intervals, only to run again after a few hours. It never did this before in our time on our server. We’re not quite sure what causes it, and IPS didn't give us much to work with in our support ticket, hence why I'm turning here. If there's any further information I should provide for assistance, I'll gladly provide what I can. We should note that there are never any System Logs relating to this, making it difficult for us to pinpoint what causes it. We have our tasks set to run with traffic. If this is an issue with our server host instead of anything IPS related, then we’re not quite sure what to do there either, but if anyone has any advice, I'd like to hear.
