>             Project: Camel
>          Issue Type: Bug
>          Components: camel-core
>    Affects Versions: 2.15.1
>         Environment: Java 8 u 40 64 bit, Linux
>            Reporter: Mateusz Nowakowski
>            Priority: Critical
>
> Having a camel context with a single route:
> {code}
>         onException(Throwable.class)
>                 .handled(true)
>                 .process(handleException()); // essentially  doing exchange.setException(someConvertedException);
>         from("direct:generalFlow")
>                 .routingSlip(property(GeneralFlowRoute.class.getName()));
> {code}
> started from Spring:
> {code}
>     <camelContext id="flows" xmlns="http://camel.apache.org/schema/spring">
>         <template id="template" defaultEndpoint="direct:generalFlow"/>
>         <routeBuilder ref="generalFlow"/>
>     </camelContext>
>     <bean id="generalFlow" class="com.blabla.GeneralFlowRoute"/>
> {code}
> During performance test both exchangesInFlightKeys  and exchangesInFlightStartTimestamps
are accumulating over time.
> But if the test is run in one thread with debug - nothing is accumulated.
> Issue found after migration from 2.14.1 to 2.15.1
