  • Emergency shutdown on secondary servers after CREATE TEXT INDEX – A secondary server goes into emergency shutdown when:
    • It is started with the -sf external_library_full_text flag, which disables loading of external libraries, and
    • The user issues a CREATE TEXT INDEX statement on the coordinator with a text configuration that uses external libraries.
    All other servers replay the DDL successfully.
  • Workaround – Start secondary nodes in the multiplex without the -sf external_library_full_text flag.
