Subject [jira] [Commented] (OAK-9575) Oak instance failed to update the lease in time
Date Fri, 24 Sep 2021 10:26:00 GMT

    [ https://issues.apache.org/jira/browse/OAK-9575?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17419712#comment-17419712

Ankush Nagapure commented on OAK-9575:

[~mreutegg] Thank you for steps, I could also reproduce this Lease failure exception by disconnecting
my VPN, also I have  implemented LeaseFailureHandler to call DocumentNodeStore.dispose()
on the old DocumentNodeStore object, and then creating new DocumentNodeStore(which internally
connect with Postgres and AWS S3 data store) and Repository objects without restarting the
application. And then I could able to test all update, insert, search operation successfully
on repository through my application.

Could you please let me know if you could see any challenges in future with this implementation.
