> Memory "leak" when setting a query timeout
> ------------------------------------------

> Key: DERBY-5375
> URL:
https://issues.apache.org/jira/browse/DERBY-5375> Project: Derby
> Issue Type: Bug
> Components: JDBC
> Affects Versions: 10.8.1.2
> Reporter: Thomas Brandl
> Labels: derby_triage10_9
>
> When setting a query timeout, a new CancelQueryTask is created and scheduled. This CancelQueryTask is still held in the java.util.Timer class's task queue even when the query is already finished until the query timeout is reached.
> For example, if i set a query timeout of 2h using statement.setQueryTimeout(7200) this means that the CancelQueryTask will remain for 2 hours even if the query is finished within 1 second. In scenarios with high load, this can lead to Out of Memory Situations.
