Mark Soderquist created QPID-6535: ------------------------------------- Summary: java.lang.OutOfMemoryError: unable to create new native thread Key: QPID-6535 URL: https://issues.apache.org/jira/browse/QPID-6535 Project: Qpid Issue Type: Bug Components: Java Broker Affects Versions: 0.32 Reporter: Mark Soderquist
Getting an OutOfMemoryError after running for several days. Attached is a thread dump showing hundreds of orphaned IoSender threads. At any given time there are fewer than 50 clients but many of them are not "well behaved". Here is the stack trace for the error but I don't really believe the LDAP calls are really the problem: 2015-05-08 03:01:19,000 ERROR [IoReceiver - /10.96.250.6:59923] (server.Main) - Uncaught exception, continuing. java.lang.OutOfMemoryError: unable to create new native thread at java.lang.Thread.start0(Native Method) at java.lang.Thread.start(Thread.java:714) at com.sun.jndi.ldap.Connection.<init>(Connection.java:234) at com.sun.jndi.ldap.LdapClient.<init>(LdapClient.java:136) at com.sun.jndi.ldap.LdapClient.getInstance(LdapClient.java:1608) at com.sun.jndi.ldap.LdapCtx.connect(LdapCtx.java:2698) at com.sun.jndi.ldap.LdapCtx.<init>(LdapCtx.java:316) at com.sun.jndi.ldap.LdapCtxFactory.getUsingURL(LdapCtxFactory.java:193) at com.sun.jndi.ldap.LdapCtxFactory.getUsingURLs(LdapCtxFactory.java:211) at com.sun.jndi.ldap.LdapCtxFactory.getLdapCtxInstance(LdapCtxFactory.java:154) at com.sun.jndi.ldap.LdapCtxFactory.getInitialContext(LdapCtxFactory.java:84) at javax.naming.spi.NamingManager.getInitialContext(NamingManager.java:684) at javax.naming.InitialContext.getDefaultInitCtx(InitialContext.java:307) at javax.naming.InitialContext.init(InitialContext.java:242) at javax.naming.InitialContext.<init>(InitialContext.java:216) at javax.naming.directory.InitialDirContext.<init>(InitialDirContext.java:101) at org.apache.qpid.server.security.auth.manager.SimpleLDAPAuthenticationManagerImpl.createInitialDirContext(SimpleLDAPAuthenticationManagerImpl.java:347) at org.apache.qpid.server.security.auth.manager.SimpleLDAPAuthenticationManagerImpl.doLDAPNameAuthentication(SimpleLDAPAuthenticationManagerImpl.java:298) at org.apache.qpid.server.security.auth.manager.SimpleLDAPAuthenticationManagerImpl.access$300(SimpleLDAPAuthenticationManagerImpl.java:72) at org.apache.qpid.server.security.auth.manager.SimpleLDAPAuthenticationManagerImpl$SimpleLDAPPlainCallbackHandler.handle(SimpleLDAPAuthenticationManagerImpl.java:470) at org.apache.qpid.server.security.auth.sasl.plain.PlainSaslServer.evaluateResponse(PlainSaslServer.java:83) at org.apache.qpid.amqp_1_0.transport.ConnectionEndpoint.receiveSaslInit(ConnectionEndpoint.java:908) at org.apache.qpid.amqp_1_0.type.security.SaslInit.invoke(SaslInit.java:112) at org.apache.qpid.amqp_1_0.transport.ConnectionEndpoint.receive(ConnectionEndpoint.java:812) at org.apache.qpid.amqp_1_0.framing.SASLFrameHandler.parse(SASLFrameHandler.java:240) at org.apache.qpid.server.protocol.v1_0.ProtocolEngine_1_0_0_SASL$4.run(ProtocolEngine_1_0_0_SASL.java:384) at org.apache.qpid.server.protocol.v1_0.ProtocolEngine_1_0_0_SASL$4.run(ProtocolEngine_1_0_0_SASL.java:380) at java.security.AccessController.doPrivileged(Native Method) at javax.security.auth.Subject.doAs(Subject.java:356) at org.apache.qpid.server.protocol.v1_0.ProtocolEngine_1_0_0_SASL.received(ProtocolEngine_1_0_0_SASL.java:379) at org.apache.qpid.server.protocol.v1_0.ProtocolEngine_1_0_0_SASL.received(ProtocolEngine_1_0_0_SASL.java:66) at org.apache.qpid.server.protocol.MultiVersionProtocolEngine.received(MultiVersionProtocolEngine.java:153) at org.apache.qpid.server.protocol.MultiVersionProtocolEngine.received(MultiVersionProtocolEngine.java:51) at org.apache.qpid.transport.network.io.IoReceiver.run(IoReceiver.java:161) at java.lang.Thread.run(Thread.java:745) -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@qpid.apache.org For additional commands, e-mail: dev-h...@qpid.apache.org
