I get the error WARNING: Failed to monitor user at slave for Free Swap Space java.io.InvalidClassException: hudson.node_monitors.SwapSpaceMonitor$MonitorTask; local class incompatible: stream classdesc serialVersionUID = 1, local class serialVersionUID = 1184166703664094906 at java.io.ObjectStreamClass.initNonProxy(ObjectStreamClass.java:562) at java.io.ObjectInputStream.readNonProxyDesc(ObjectInputStream.java:1583) at java.io.ObjectInputStream.readClassDesc(ObjectInputStream.java:1496) at java.io.ObjectInputStream.readOrdinaryObject(ObjectInputStream.java:1732) at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1329) at java.io.ObjectInputStream.readObject(ObjectInputStream.java:351) at hudson.remoting.UserRequest.deserialize(UserRequest.java:182) at hudson.remoting.UserRequest.perform(UserRequest.java:98) at hudson.remoting.UserRequest.perform(UserRequest.java:48) at hudson.remoting.Request$2.run(Request.java:326) at hudson.remoting.InterceptingExecutorService$1.call(InterceptingExecutorService.java:72) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:303) at java.util.concurrent.FutureTask.run(FutureTask.java:138) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:619) It seems that this is a bug. I am not familiar enough with jenkins to assess if it can cause great problems, or not. BR, David Project: Jenkins Priority: Minor Reporter: David Gang
