We are using ServiceMix 5.1.1 and frequently face high CPU usage on the java process. 

The camel integrations are done using blueprint xml and there it also communicates with  SolR which is present on another server. 

I took the thread dump and isolated the thread which was taking up more than 99% of the CPU, and these are its details
