Occasionally a message will not appear for some users. I suspect that it isn't getting into the cache file. Possibly related: an idle user may send a message, but it won't display until the user sends a second message.

After discussing the issue with Justin Randell, I learned that the cache files don't actually store anything. They just show when the last update was made.

This is most likely caused by large numbers of simultaneous queries to an extremely large database table.

So the solution is to archive chats on a regular basis. I would suggest creating chats for specific time periods and archiving them at the end of each time period.
