Cannot start/stop/restart cryosparcm

Troubleshooting

Hi folks,

I installed cryosparc v2 a few days ago and it was running just fine. Today none of the commands cryosparcm start/stop/restart work. Please see error below. Have you experienced this?
Thanks,
Elena

cryosparcm start

If you would like to restart, use cryosparcm restart

Hi @zehre

A cryoSPARC process may have been orphaned. You will have to kill it.

Can you please try:

cryosparcm stop

Then, delete the unix:///tmp/cryosparc-supervisor-2d5891e41f1cbf50751930c18d4147eb.sock file.

Finally, you may need to kill any other remaining processes that may be interfering. You can find the process IDs using:

ps -ax | grep “supervisor” (kill only processes that are related to cryoSPARC 2)

cryosparcm start

Please let us know if that works.
