Huge org.springframework.boot.loader.LaunchedURLClassLoader memory usage

Question

Over time my unused running my Spring Boot v1.3.2 application gradually increases memory consumption until it eventually falls over. By unused I mean no client requested are being served apart from the regular ping of the /health end point.

According to the Eclipse Memory Analyser, org.springframework.boot.loader.LaunchedURLClassLoader is taking up a massive 920MB.

It appears as though Spring Boot is continually loading classes

Any ideas what's going on?

EDIT

Looks like it's Spring Cloud Consul that's causing the issue:

Appears to be a memory leak in Spring Cloud Consul. Raised issue https://github.com/spring-cloud/spring-cloud-consul/issues/183
