I did write a simple app using Spring Boot (1.2.7.RELEASE) and Apache Camel (2.15.0). The app is simple and has only 1 route: a timer will invoke a method on a bean every 1s. The method invoked will use ProducerTemplate to ssh into a remote machine, execute a small script, and print out the output to the console. Simple, right? However, when profiling this, I can see the number of threads! It seems like any threads created for the ssh are never killed, but parked instead. Because of that I run OOM pretty quickly with an error:
Exception in thread "Thread-341" java.lang.OutOfMemoryError: unable to create new native thread More description and profiler results can be found on stackoverflow: http://stackoverflow.com/questions/33671567/spring-boot-camel-producertemplate-memory-leak I think this is a bug, as from the documentation I can't see that I am using the ProducerTemplate wrongly. Or am I? If so, please tell me. If I am doing things right and it seems like a bug, I will submit it... -- View this message in context: http://camel.465427.n5.nabble.com/Spring-Boot-Camel-producerTemplate-ssh-spawning-thousands-of-threads-tp5773741.html Sent from the Camel - Users mailing list archive at Nabble.com.
