GitHub user Susmit07 edited a discussion: Memory Leak for Pekko Shardedc cluster

Hellp Team


We were tying large file upoad 15-20gb using HDFS as source and S3 as sink with 
 S3 multipartApi, but I am seeing leaking resources

```
One instance of java.util.zip.ZipFile$Source loaded by <system class loader> 
occupies 4,94,11,544 (55.80%) bytes. The instance is referenced by 
org.apache.pekko.dispatch.MonitorableThreadFactory$PekkoForkJoinWorkerThread @ 
0x6c33b5548 cef-datasync-downloader-pekko.actor.default-dispatcher-6, loaded by 
jdk.internal.loader.ClassLoaders$AppClassLoader @ 0x6c34cda68.
```
