Container immediately crashes due to /tmp error

[unusualcrow]

Running on OpenMediaVault. Found 2 other reports of this issue in the SDR Enthusiasts Discord server, with no solutions.

My docker compose:

  picard:
    image: mikenye/picard:latest
    container_name: picard
    environment:
      - USER_ID=${PUID}
      - GROUP_ID=${PGID}
      - TZ=${TZ}
      - CLEAN_TMP_DIR=0
    volumes:
      - "${ROOT}/config/picard:/config:rw"
      - "${ROOT}/database/Music:/storage:rw"
    ports:
      - 5800:5800

vars: PUID=1002 PGID=1002 TZ=America/New_York ROOT=/Prim5/Plex
