If server load (unix) goes above 17.0 (high by any standards) or more than 900 simultaneous users are logged on (never achieved) then you will get the server busy message. The busiest time of day for the server is between 1130 and 1330 UTC. The server load is an average of the work being done by the processors. Normal safe activity is usually below 1.0 but most of the time the PPRune server is running at about 4.0 to 5.0. When 17.0 is reached your request is not processed and you get the message. It often drops down quite quickly to manageable levels and you should try again after about 20-30 seconds if you get the message. If the server load is high then you will also find the response time is much slower.
The current server is not even a year old yet and already I am having to start preparations for a server upgrade. I would love to go to an all singing, all dancing mega powerful server but the costs are prohibitive at the moment and therefore i have to look at gradual upgrades as and when they are required.
Those of you who remember the previous servers and the problems caused when they were overloaded will be quite happy with the current gentle way you are told about the problem. With regards to the long post/lost post dilemma it is always the case that you learn the hard way to save your work before submitting it if it is long.
