MOHAMMED SOHAIB reopened CAMEL-13781:
-------------------------------------
Team,
I have compiled our application code with the latest camel-core 2.24.1 with
JDK 7 and the build generation got failed.
If I use the JDK 8 for camel-core 2.24.1 version of jar files, then the code
got compiled and build generated successfully.
We are using Java 7 in our applications and our applications are deployed into
Websphere with JDK 7.
I have attached the code snippets here where we are facing the memory leaks in
the Java Hash Map.
Please refer the Code Snippet 2 highlighted piece of code. Plz review and
suggest and if we can use the garbage collector into this hasp map.
I am trying to reproduce this issue with 2.24.1 but when I deploy this jar file
with the application server WAS, our application is not able to start. Getting
Library mismatch issue.
Regards,
Md Sohaib.

> 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
> *+Leak suspect 3.+*
> A Linked List Data Structure Detected.
> 228,816,192 bytes (8.7 %) of Java heap is used by 759 instances of
> org/apache/camel/com/googlecode/concurrentlinkedhashmap/ConcurrentLinkedHashMap$Node
> Contains 2 types of the following objects:
> - 759 instances of java/lang/String holding 139,656 bytes
> - 759 instances of
> org/apache/camel/com/googlecode/concurrentlinkedhashmap/ConcurrentLinkedHashMap$WeightedValue
> holding 228,658,112 bytes
> -Contained under array of java/util/HashMap$Entry holding 1,403,578,672 bytes
> at 0x70e6cd110
> ========================================================
>
> Kindly review this problem and suggest possible solutions as soon as possible.
