After some more diagnostics we found that the graphics card memory was full during the large intervals. As we did not manage to monitor the graphics card memory usage in normal operation, it is not entirely certain that this is the cause, however since the normal memory was slowly being filled during the large intervals this seems to be the main cause. I am wondering if there are typical settings that we can modify in order to reduce the graphics card memory footprint? If not, we should consider updating our hardware I guess.
