> 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
