[jira] [Created] (CAMEL-14000) ServicePool can cause memory leak

John Poth created CAMEL-14000:
---------------------------------

             Summary: ServicePool can cause memory leak
                 Key: CAMEL-14000
                 URL: https://issues.apache.org/jira/browse/CAMEL-14000
             Project: Camel
          Issue Type: Improvement
    Affects Versions: 3.0.0.RC1, 2.24.2
            Reporter: John Poth


The [ServicePool|[https://github.com/apache/camel/blob/master/core/camel-base/src/main/java/org/apache/camel/impl/engine/ServicePool.java#L50]] or (DefaultServicePool in 2.x) uses a unbounded ConcurrentHashMap to cash producers. This can cause memory leaks in highly dynamic routes using recipient lists creating many temporary endpoint which will never be evicted even when the route stops. Even though workarounds exists, we might consider using an LRUCache for eviction.
