I had checked with Gunnar and Jiri. As Jiri suggested , he asked to log a jira to track the issue.

We are running debezium mysql connector in a two node machine. If we start and stop in very next time it works. If we stop
the connector after 1day of start And then we try to start it . It throws below error.
Debezium version: 0.8.1
