Implementation: 0 [...] (ad infinitum) I was definitely running Rstudio desktop in x2go session, but don't know if it was generating these messages. Expected behaviour: Too quickly appearing messages from the same process should not end up in the log file. systemd-journald if I am correct has such a feature. I am not reporting it to qtwebengine or Rstudio right now. Will do if encouraged in your comments. Regards, Piotr
