How to kill a ghost instance?

Hi there,

I have a project that has been deleted, however, when I viewed cryosparcm log command_core output. It still shows some ghost processes running on this project. Could you let me know what is the best solution for this problem other than reinstalling cryosparc? Thanks! Please let me know if additional information is needed.

Below is the log output:

"[EXPORT_WORKSPACES] : Exporting all workspaces in P21…

Hi @wxh180,

Did you have any live sessions in P21?

Hi @stephan,
Yes. That seems to be the problem. I don’t know why live is still running after a restart and did not show up on the resource page.

Hi @wxh180,

Were you able to stop the live session? It seems like the live session was not paused before the project was deleted, is that correct? Restarting cryoSPARC does not turn off live sessions, it only stops any related jobs (e.g., RTP Worker, Streaming 3D Refinement, etc.) Can you provide us with the logs of command_core and command_rtp? (cryosparcm log command_core, cryosparcm log command_rtp)
