Re: Failed to monitor for Free Swap Space
I have just come across this on two types of host.
First on Illumos(Smartos)/LX zones, it occasionally reports gigantic free memory (probably a bug), after which the buld log stops updating
{{Failed to monitor Triton-455640a8f44f for Free Swap Space java.util.concurrent.ExecutionException: java.io.IOException: Failed to parse: '18446744073709099244' out of 'MemFree: 18446744073709099244 kB' at hudson.remoting.Channel$2.adapt(Channel.java:813) at hudson.remoting.Channel$2.adapt(Channel.java:808) at hudson.remoting.FutureAdapter.get(FutureAdapter.java:59) at hudson.node_monitors.AbstractAsyncNodeMonitorDescriptor.monitor(AbstractAsyncNodeMonitorDescriptor.java:96) at hudson.node_monitors.AbstractNodeMonitorDescriptor$Record.run(AbstractNodeMonitorDescriptor.java:305) Caused by: java.io.IOException: Failed to parse: '18446744073709099244' out of 'MemFree: 18446744073709099244 kB' at org.jvnet.hudson.ProcMemInfo.monitor(ProcMemInfo.java:56) at hudson.node_monitors.SwapSpaceMonitor$MonitorTask.call(SwapSpaceMonitor.java:113) at hudson.node_monitors.SwapSpaceMonitor$MonitorTask.call(SwapSpaceMonitor.java:103) at hudson.remoting.UserRequest.perform(UserRequest.java:120) at hudson.remoting.UserRequest.perform(UserRequest.java:48) at hudson.remoting.Request$2.run(Request.java:326) at hudson.remoting.InterceptingExecutorService$1.call(InterceptingExecutorService.java:68) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745) at ..remote call to Triton-455640a8f44f(Native Method) at hudson.remoting.Channel.attachCallSiteStackTrace(Channel.java:1416) at hudson.remoting.UserResponse.retrieve(UserRequest.java:220) at hudson.remoting.Channel$2.adapt(Channel.java:811) ... 4 more}}
I also now get this on Jenkins 2.x on windows slaves:
