The dedicated server hosting the eduBuzz WordPress Multi-User blog system is now spending a lot of its time quite heavily loaded, although performance hasn’t been noticeably affected. Right now, for example, the CPU load is at over 90%, and it’s nearly midnight.
Working on it yesterday from Tranent Primary School, on a very slow network connection, we hit some problems with sessions breaking. WordPress displayed a screen saying, in effect: “you can’t connect to the database – maybe your password’s wrong?”
I guess these were due to time-outs occurring, perhaps due to the combination of server response time delays coinciding with network delays. Once the network speeded up, everything went back to normal.
