    [ https://issues.apache.org/jira/browse/CAMEL-13781?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16890687#comment-16890687 ] 

Andrea Cosentino commented on CAMEL-13781:
------------------------------------------

Use a new version of Camel. 2.17.7 is really old.

If you need a fix/solution/suggestion "as soon as possible" you can use commercial support.

> Dear Team,
> There is frequent memory leakage problem on production WAS server and We have analyzed the heap dump, thread dumps and garbage collection logs and below are the Observations from our analysis.
> We observed the memory leakage problem with the below package,
> *org/apache/camel/com/googlecode/concurrentlinkedhashmap/ConcurrentLinkedHashMap*
>  
> The memory leakage might be happening in the camel jar file *"camel-core-2.17.7.jar"* as per the leakage suspect analysis which is used in our custom application name "RestWebServices"
> +*Below are the observations from the logs analysis.*+
> *+Leak suspect 1.+*
>  1,403,578,672 bytes (53.36 %) of Java heap is used by 254 instances of java/util/HashMap$Entry
>  Contains an instance) of the leak suspect:
>  - org/apache/camel/com/googlecode/concurrentlinkedhashmap/ConcurrentLinkedHashMap$Node holding 228,815,984 bytes at 0x71fb89c88
>  
>  *+Leak Suspect 2.+* 
> 977,860,416 bytes (37.17 %) of Java heap is used by 9,682 instances of org/apache/http/impl/conn/PoolingHttpClientConnectionManager
