Description

A scheduled batch is attempting to start the slave agent with the following script:

taskkill /f /im "EXCEL.exe"
taskkill /f /im "ipy.exe"
taskkill /f /im "jp2launcher.exe"

javaws http://172.16.8.57:8080/computer/SSW73210/slave-agent.jnlp

When the slave agent opens, it fails to do anything but the enclosed error. After rebooting, this issue fails to reproduce, but this seems dramatically more common when the slave is left on overnight.

I reproduced this error on win10 removing the slave-agent.jnlp or having more than 1 of this files.

The problem is that the slaves loses somehow the connection configuration to the master so this error is shown.

My solution was to create a new agent slave, so a new .jnlp can be downloaded, and this one will be well configured so it will work.

If the .jnlp doesn't show you in jenkins to download, you can try with the command :

java -jar agent.jar -jnlpUrl http://jenkinsurl:port/computer/windows-agent/slave-agent.jnlp -secret xxxxxxxx -workDir "C:\JenkinsSlave"

It looks like people are seeing a number of different issues, generally involving the same error message. Some people report success by tracking down a different machine running the same agent. Some find that some cleanup corrects the problem, though it's not clear just what cleanup is required. In some cases it probably involves a connection timeout and the server thinks an old instance of the agent is still connected.

As Oleg said earlier, to get anywhere with this will require clear reproduction documentation and both agent and master logs. Information on whether it is specific to a certain type of platform or environment would also be important. I see some mention of different versions of Windows OSes but it's not clear if it's just a Windows issue and if it only occurs in some Windows environments or versions.

FYI in case it helps any – I just had to go through a big diag effort on my site with a bunch of windows JNLP agents that stopped working sometime in past few days with the same above failures/errors.

After a long set of rabbit trails - what I found in my case – the problem wound up being reverse DNS resolution stopped working (unrelated local problem – "It's always DNS", right?) - but that inability to reverse resolve the connecting client (windows box) was causing the JNLP server side to drop the connection.

Just wanted to add this here in case it helps anyone else with future similar issues if it happens to be related.

Not sure if same issue, but the service is dying on a server 2012 node. It is set to restart and eventually it will connect but again die very frequently. Below is the slave error and slave-wrapper error logs:

I have the same problem. After change org.jenkinsci.remoting.protocol.ProtocolStack#handshakingTimeout to more then 20s,then it connected. My conclusion is that the connect will take more then 10s sometimes based on the network driver,but the default 'final ' value is 10s , so it will timeout and closed.

The final reason is java.net.InetSocketAddress#getHostName invoked by org.jenkinsci.remoting.engine.JnlpProtocol4Handler#createSSLEngine blocked so much time.
