When submitting a proposal and finishing it, an error will appear in the database.

DB Error: ERROR: index “paper_search_object_keywords_keyword_id” Contains Unexpected zero page at block 283 SUGERENNCIA: Please REINDEX it.

Versión del OCS
2.3.6.0 (marzo 15, 2018 - 09:19 )
OS: Linux red hat enterprise 7
database: postgres

You can help me this error occurs after restarting the system.

Hi @proyrevistas,

This is a database-level error message, not an OCS-level message; see e.g. https://stackoverflow.com/questions/47510124/postgres-index-contains-unexpected-zero-page-at-block-exceptions for details.
