Seems akka Remoting still keep some memory object even sender called actorSystem.shutdown. test as below
akka version 2.3.4 Receiver(only 1) <==========> Sender (multiple) We keep create sender and (around *300k* Senders) each sender behavior same way - Connect to Receiver,Send serveral messages, shutdown actor system When all *300k* Senders run completed. The Receiver consumed lot of memory after full gc (456 MB). 2.634: [GC 15424K->3809K(58816K), 0.0184900 secs] 3.411: [GC 19233K->6358K(58816K), 0.0095820 secs] .... 7040.107: [GC 335042K->250050K(333056K), 0.0419540 secs] 7040.149: [Full GC 250050K->219156K(346368K), 2.2192770 secs] ... 42445.401: [GC 476143K->461016K(628928K), 0.0100950 secs] 42445.411: [Full GC 461016K->456824K(651840K), 1.4056710 secs] run "jmap -dump:live,format=b,file=akkatestheap.bin 28819" and "jhat akkatestheap.bin" to analyze the heap content, find there are plenty of " *akka.remote.transport.netty.TcpAssociationHandle*" which contains "remoteAddress". In fact all Senders' actor system were shutdown. Why the Receiver actor system still save so many Senders' address? Is this a *memory leak*? -- >>>>>>>>>> Read the docs: http://akka.io/docs/ >>>>>>>>>> Check the FAQ: >>>>>>>>>> http://doc.akka.io/docs/akka/current/additional/faq.html >>>>>>>>>> Search the archives: https://groups.google.com/group/akka-user --- You received this message because you are subscribed to the Google Groups "Akka User List" group.
