we are using **camel direct component** in our project.

Application will work fine most of the time.
But sometimes services won't work because of following exception.
if we restart server again things will go normal.

we are not following any route startup order to start camel routes. All routes will load at deployment time only.

**we are using camel 2.16.1 version.**

Could any one suggest what causing this issue and why it is occurring often. 

**Caused by: org.apache.camel.component.direct.DirectConsumerNotAvailableException: No consumers available on endpoint: Endpoint[direct://framework-logger-service].**
