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.+*
