I'm using confluence running on centos 6.5 in our company using the embedded database. It was working fine till last day. We added a lot of stuffs into it. But last day I just disabled the firewall from the GUI. Then I turned it back on but when I checked the IP tables there was no port 8090 opened it. I opened port 8090. So, I can access confluence remotely. But the problem is I cant add how to articles and meeting notes. How will I resolve this issue. Is there any chance for database to be full of memory since I haven't migrated to production environment yet. Please give me a helping hand to resolve the issue. Thanks.
