This means that metadata extrator is trying to extract the metadata and getting failed either due to not able to read the content or configuration is not done correctly. 

However, it should not cause alfresco to crash. Could you please enable following logs, review the logs and share the logs alfresco.log, catalina.out log so it can be reviewed ? Also are using local transformation service or legacy ?

log4j.logger.org.alfresco.repo.content.metadata.AbstractMappingMetadataExtracter=DEBUG

or
