V3.2.0 Fresh Install - cryoSPARC not starting, only database running

Install, Configure and Update
1

Hello,

After freshly installing cryosparc following the install instructions and starting cryosparc via cryosparcm start, cryosparc only starts the database and command_core.

Output from cryosparcm status:

CryoSPARC System master node installed at
/ibex/scratch/projects/c2030/cryosparc/cryosparc_master
Current cryoSPARC version: v3.2.0
----------------------------------------------------------------------------

Hi @zahodnbd,

This may be due to a zombie process that is preventing cryoSPARC from running correctly.

  1. Ensure cryoSPARC is turned off:

cryosparcm stop

  1. Then, ensure no zombie processes are still running. Kill the processes if they are.

ps -ax | grep “supervisord” (kill only the process that is running from your cryoSPARC install)
ps -ax | grep “cryosparc_command” (kill all the matching processes related to your cryoSPARC
instance)
ps -ax | grep “mongod” (kill only the process running your cryoSPARC database)

e.g. kill 82681

  1. Remove the socket file inside the /tmp folder

/tmp/cryosparc-supervisor...XXX.sock

  1. Start cryoSPARC:

cryosparcm start

cryosparcm status

Please let me know if that helps.
