I’m able to kill it even with SIGTERM. I don’t see any spike in CPU usage.
I see a problem on both mongosh 1.0.4 and 1.0.5 on Ubuntu 18.04 on a few different machines. Usage of --nodb or --norc does not change the behavior.
I don’t see anything relevant in the log. The last entry is
{“level”:30,“time”:1630050655432,“pid”:15175,“hostname”:"",“name”:“mongosh”,“msg”:“mongosh:evaluate-input {“input”:“1”}”,“v”:1}
