We had an incident with LDAP and it hanged during sending out notifications to users. It would be good to have decent timeouts set for those connections.
http://docs.oracle.com/javase/7/docs/technotes/guides/jndi/jndi-ldap.html: com.sun.jndi.ldap.read.timeout and com.sun.jndi.ldap.connect.timeout I suspect that it's not possible to set them via system properties. jstack slice: "pool-1-thread-500757" prio=10 tid=0x00007fae7cf13800 nid=0xe334 runnable [0x00007fae91222000] java.lang.Thread.State: RUNNABLE at java.net.SocketInputStream.socketRead0(Native Method) at java.net.SocketInputStream.read(SocketInputStream.java:150) at java.net.SocketInputStream.read(SocketInputStream.java:121) at sun.security.ssl.InputRecord.readFully(InputRecord.java:442) at sun.security.ssl.InputRecord.read(InputRecord.java:480) at sun.security.ssl.SSLSocketImpl.readRecord(SSLSocketImpl.java:927) - locked <0x00000004cf48ff20> (a java.lang.Object) at sun.security.ssl.SSLSocketImpl.performInitialHandshake(SSLSocketImpl.java:1312) - locked <0x00000004cf48ff38> (a java.lang.Object) at sun.security.ssl.SSLSocketImpl.writeRecord(SSLSocketImpl.java:702) at sun.security.ssl.AppOutputStream.write(AppOutputStream.java:122) - locked <0x00000004cf48ff50> (a sun.security.ssl.AppOutputStream) at java.io.BufferedOutputStream.flushBuffer(BufferedOutputStream.java:82) at java.io.BufferedOutputStream.flush(BufferedOutputStream.java:140) - locked <0x00000004cf48ff68> (a java.io.BufferedOutputStream) at com.sun.jndi.ldap.Connection.writeRequest(Connection.java:429) - locked <0x00000004cebefba8> (a com.sun.jndi.ldap.Connection) at com.sun.jndi.ldap.Connection.writeRequest(Connection.java:402) at com.sun.jndi.ldap.LdapClient.ldapBind(LdapClient.java:352) - locked <0x00000004d058c980> (a com.sun.jndi.ldap.LdapClient) at com.sun.jndi.ldap.LdapClient.authenticate(LdapClient.java:210) - locked <0x00000004d058c980> (a com.sun.jndi.ldap.LdapClient) at com.sun.jndi.ldap.LdapCtx.connect(LdapCtx.java:2740) 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 com.pmease.quickbuild.plugin.authenticator.ldap.LdapAuthenticator.getEmail(LdapAuthenticator.java:462) at com.pmease.quickbuild.plugin.authenticator.ldap.LdapAuthenticator$$EnhancerByCGLIB$$9ba8a4c2.CGLIB$getEmail$2(<generated>) at com.pmease.quickbuild.plugin.authenticator.ldap.LdapAuthenticator$$EnhancerByCGLIB$$9ba8a4c2$$FastClassByCGLIB$$b19a6824.invoke(<generated>) at net.sf.cglib.proxy.MethodProxy.invokeSuper(MethodProxy.java:215) at com.pmease.quickbuild.DefaultScriptEngine$Interpolator.intercept(DefaultScriptEngine.java:270) at com.pmease.quickbuild.plugin.authenticator.ldap.LdapAuthenticator$$EnhancerByCGLIB$$9ba8a4c2.getEmail(<generated>) at com.pmease.quickbuild.DefaultBuildEngine.getUser(DefaultBuildEngine.java:713) at com.pmease.quickbuild.DefaultBuildEngine.sendNotifications(DefaultBuildEngine.java:756) at com.pmease.quickbuild.DefaultBuildEngine.process(DefaultBuildEngine.java:409) at com.pmease.quickbuild.DefaultBuildEngine.access$000(DefaultBuildEngine.java:129) at com.pmease.quickbuild.DefaultBuildEngine$2.run(DefaultBuildEngine.java:1051) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:471) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:334) at java.util.concurrent.FutureTask.run(FutureTask.java:166) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:724) |
