+ | Sometimes, particularly if the previous S800 DAQ session ended in an uncontrolled way, there may be old processes running (CCUSB and/or VMUSB and/or S800 event builder) that will prevent Readout GUI to begin a run. Whenever this happens (typically after clicking '' | ||
+ | - Exit your Readout | ||
+ | - Type '' | ||

+ | - You will see a list of ringbuffers with information about their status (see figure below). Check that the producer value of each ringbuffer (see column '' | ||

- | This is the only information available to the tcp protocol, but the pid of the processes responsible for these connections can be investigated by using the following commands: | ||

- | 2. Do **lsof -i | grep port** (where port is replaced by the local port information obtained from the status gui. This will look similar to: | ||

- | This tab allows forced control of the Readout GUI, and is for advanced users only. In the event that the run must be stopped, or the DAQ software exited without access to the Readout GUI itself these buttons may be used to perform these actions. The run MUST be ended before using the Force Exit button, or it is likely that the USB crate controllers will become stuck in DAQ mode and the crates will have to be reset. | ||
