Webservice response File Descriptor leak ---------------------------------------- Key: WFLY-8160 URL: https://issues.jboss.org/browse/WFLY-8160 Project: WildFly Issue Type: Bug Components: Web Services Affects Versions: 9.0.0.Final, 9.0.2.Final, 10.1.0.Final Environment: JDK: jdk1.8.0_121, jdk1.8.0_66 WilfFly : wildfly-10.1.0.Final, wildfly-9.0.2.Final , wildfly-9.0.0.Final OS: Red Hat Enterprise Linux Server release 7.1 (Maipo) Hardware: 64 bit 4 core Reporter: Mahesh Reddy Assignee: Alessio Soldano Attachments: BioMatcherWebserviceImpl.java, SOAP_REQUEST.txt, SOAP_RESPONSE.txt, file-leak-detector_output.txt We are getting File descriptor leak when wildfly responds to webservice call. I think this happens if the webresvice response is huge complex structure, I confirmed by adding the sleep just before the returning from the webservice method and checking lsof -p <pid>, And again checking it after client receives the response,. I notice for each webservice call, 2 file descriptors are open and never closed.
