My server supports 1500 users and growing each day, across 12 sites and in one site after 8 days of openfire running I have 4 users who cannot connect anymore to the server. They login only to be booted out right away, if I restart openfire they are good for another 8 days.
I am running Openfire 3.9.1 on Ubuntu 12.04 x64 and I have no idea what is causing this issue only for these 4 people on the same VLAN in the same site and only after 8 days. There are no firewalls between them and the server but there are switch based ACL’s but if those were the issue why does restarting openfire fix it for 8 days.
Server is on a VM with 8 cores and 12GB of ram assigned to it. The CPU’s on avg site 20-40% depending on the time of day.
