# Summary I'm working on upgrading OpenWhisk to Akka 2.6.20 and Scala 2.13 and experienced the issue with OpenWhisk invokers consuming all available g1-old heap size after running for a couple of days with active traffic. Doing heap profiling I got the following suggestions from Heap Hero: ``` One instance of akka.actor.LocalActorRef loaded by jdk.internal.loader.ClassLoaders$AppClassLoader @ 0x3c05c5018 occupies 20,136,784 (18.14%) bytes. The memory is accumulated in one instance of scala.collection.immutable.RedBlackTree$Tree, loaded by jdk.internal.loader.ClassLoaders$AppClassLoader @ 0x3c05c5018, which occupies 20,132,728 (18.14%) bytes. ``` Further analysis with Eclipse Memory Analyzer shows the following: <img width="1186" alt="Screenshot 2023-08-03 at 11 26 51 AM" src="https://github.com/apache/openwhisk/assets/2736528/51d8fa89-c0d2-4385-b6d4-9c5dcd83e433";> <img width="644" alt="Screenshot 2023-08-03 at 11 29 54 AM" src="https://github.com/apache/openwhisk/assets/2736528/267f6826-c0fa-42a9-87d3-331e9682b9a0";> <img width="737" alt="Screenshot 2023-08-03 at 11 29 34 AM" src="https://github.com/apache/openwhisk/assets/2736528/278d6cd9-50e2-4fab-88e6-4742576248bc";> ## Environment details: * Scala 2.13 * Akka 2.6.20 * Akka HTTP 10.2.10 * Akka Management 1.1.4 Any suggestions on where I should look to find the root cause of this memory leak? -- This is an automated message from the Apache Git Service.
