There is currently an issue which can cause effects such as stun, etc to not wear off. We are aware of the issue and are in the process of implementing a hotfix.
Until this hotfix please refrain from entering combat on both PvP and PvE servers.
A full PvP ban is also in place until this issue is confirmed resolved.
A public list of what directives are in effect can be found here.
