We will be rolling out a hot-fix, currently scheduled for Tuesday, May 9th at 3:00 PM PDT (10 PM UTC), to fix an issue with server stability encountered over the weekend.
Using the additional logging and diagnostics introduced during the brief downtime on Sunday we identified an issue with the system used for querying pilot data within the frontend menu of the MWO client; this system is used to track your current Contract or Faction allegiance, Unit status, and so on.
The server instability came as a result of this system being utilized by the Floating Chat feature released in our April patch, causing an excessive number of pilot data queries per-second and an overload of the database systems due to the number of Faction Chat participants. This led to a number of issues you may have encountered over the weekend, from mass-disconnections to sluggish performance of the menu systems.
Today's hot-fix should resolve these issues as we look ahead to the final weekend of Tukayyid 3.
In addition to the above this hot-fix will also include the following fixes:
Floating Chat: Fixed an issue where players would be required to close and re-open Chat to make the tabs appear correctly after logging out and logging back in (without closing the client).
Floating Chat: Fixed an issue where the Unit Message of the Day would be cut off.
