Description
This is a regression affecting the open source OpenSVC monitoring database
The issue is triggered with a 20 rows scheduler table that is not inside opensvc code but a generic web2py internal scheduler
CREATE TABLE `scheduler_task` ( |
`id` int(11) NOT NULL AUTO_INCREMENT, |
`uuid` varchar(255) DEFAULT NULL, |
`args` longtext DEFAULT NULL, |
`vars` longtext DEFAULT NULL, |

`stop_time` datetime DEFAULT NULL, |
`repeats` int(11) DEFAULT NULL, |
`retry_failed` int(11) DEFAULT NULL, |
`period` int(11) DEFAULT NULL, |
`timeout` int(11) DEFAULT NULL, |
`sync_output` int(11) DEFAULT NULL, |
`times_run` int(11) DEFAULT NULL, |
`times_failed` int(11) DEFAULT NULL, |
`last_run_time` datetime DEFAULT NULL, |
`prevent_drift` char(1) DEFAULT NULL, |

PRIMARY KEY (`id`), |
UNIQUE KEY `uuid` (`uuid`), |

KEY `idx_expire` (`status`,`stop_time`) |
) ENGINE=InnoDB AUTO_INCREMENT=166 DEFAULT CHARSET=utf8 COLLATE=utf8_general_ci; |
The affected user capture a partial processlist before restarting the server
