After running for a long time (more than 4 weeks), server says:
WARN 13:22:38,045 | org.apache.camel.component.direct.DirectProducer | No consumers available on endpoint: Endpoint[direct://mailserver] to process: Exchange[Message: org.apache.james.core.MailImpl@6a9e9a09]
INFO 13:22:38,045 | james.smtpserver | Successfully spooled mail Mail1278933758045-65 from ... on 127.0.0.1 for [firstname.lastname@example.org]
Mail are not delivered in the user inbox.
No file in var/...
After start/stop, everything is ok.
This seems unpredicatable.
Maybe linked to https://issues.apache.org/activemq/browse/CAMEL-2854?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=60350#action_60350 ?
