Sometimes I will see RStudio Connect with processes in the admin tab where the Type is listed as "unknown job".
I notice this when I have content (APIs) set to use min_proc=1, but that's only through association and I haven't fully tested that relationship. I see this on my staging server, and not my production server. But the production server currently does not have any APIs set to use min_proc=1.
Oddly, I also cannot find these "unknown job" process IDs in the backend. For example:
sudo grep 27923 /var/log/rstudio-connect*
sudo grep 27923 /var/log/syslog*
Both return no results.
I'm using RSConnect 1.8.6.6 on Ubuntu 18.04.
