Tom Manning created an issue   Jenkins / JENKINS-50219 Jenkins agent windows service fails to restart with an unhandled COMException in WinSw's log Issue Type: Bug Assignee: Oleg Nenashev Components: windows-slave-installer-module Created: 2018-03-16 13:48 Environment: Jenkins 2.9.84 windows-slave-installer 1.9.2 jenkins-slave.exe running on Windows 10 + jre 1.8.0.161 under local admin credentials. Priority: Minor Reporter: Tom Manning We have noticed that our Windows 10 nodes have been intermittently failing to come back online after Jenkins / master restarts.   The following entries are shown in WinSw's Jenkins-slave.wrapper.log file at the time of the failures. In particular it appears that the unhandled COMException is preventing the service restarting successfully.   2018-03-16 12:26:38,011 DEBUG - Starting ServiceWrapper in the CLI mode 2018-03-16 12:26:38,589 INFO  - Restarting the service with id 'jenkinsslave-c__jenkins' 2018-03-16 12:26:38,682 DEBUG - Completed.

When a secondary WinSw process is run with the "restart!" parameter by Jenkins.   if (args[0] == "restart") {     Log.Info("Restarting the service with id '" + d.Id + "'");     if (s == null)         ThrowNoSuchService();     if(s.Started)         s.StopService();     while (s.Started)     {         Thread.Sleep(1000);         s = svc.Select(d.Id);     }     s.StartService();     return; } We are currently able to work around the problem by restarting the service manually on affected nodes.   Add Comment   This message was sent by Atlassian JIRA (v7.3.0#73011-sha1:3c73d0e) -- You received this message because you are subscribed to the Google Groups "Jenkins Issues" group.
