Recently I've noticed that one of my crunchers will be happily "bouncing off the limits". It will then report a few tasks, and thus request a few new tasks. The server responds with "Scheduler request completed: got 0 new tasks", followed quickly by "No tasks sent", messages about type of task not available, then finally "This computer has reached a limit on tasks in progress". The last statement is incorrect, as a quick look see shows that the computer no longer has 200 tasks "in progress", but somewhat less. This will repeat for a couple of cycles before it gets enough tasks to return it to 200 in progress. This appears to most commonly happen when there are about 10 tasks reported in one cycle.

It may get the limit reached message even if there are less than 200 because the limits are not really 200, its 100 for GPU and 100 for CPU, and when one of them is reached you get that message if the client was asking for both kind of work or for the one that is in the limit...

Most common situation is when the CPU has enough work for the cache size choosen (and this amount could be less than 100 if your cache is not set to a very hughe size or there are not so many CPU cores in that host) and then the only real limit in effect is the one for the GPU.

Rob, go to the Projects tab and highlight Seti@home. When your communication deferred time gets downs to less than 3 seconds, click on the Update button on the Projects tab. If there is work, you should see both GPU and CPU WUs coming through.
