Subject [jira] [Commented] (CONNECTORS-1581) [Set priority thread] Error tossed: null during startup
Date Wed, 13 Feb 2019 12:29:00 GMT

    [ https://issues.apache.org/jira/browse/CONNECTORS-1581?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16767116#comment-16767116
] 

Markus Schuch commented on CONNECTORS-1581:
-------------------------------------------

Was not able to reproduce. Everything was cleaned up properly after deleting multiple jobs
with >1.000.000 records, even when i poked around with database, database connection, the
manifoldcf process and the outputrepo.

It is possible, that the error occured while using an older version of the mariadb jdbc driver
(which we updated frequently in our setup), but since lack of time i won't invest to explore
this further.
