svn rev 3577 avoids a NPE if a resource's type is null. This just avoids a NPE exception but it doesn't address the underlying problem - WHY is this type null in the first place? Somehow the type looks to be null in inventory.dat when clearly it should not be. I think it might be because I killed the agent prior to an initial clean shutdown. If a clean agent (one without inventory.dat) starts but gets killed without shutting down nicely the first time, its original inventory.dat with unsync'ed types are in inventory.dat. I think we need to make sure we cleanly shutdown the agent for a first time in order for it to write out inventory.dat with the full types. This is just a guess. This might be related to RHQ-979 workaround suggestion: better error handling, such as continuing as if the inventory.dat file didn't exist and renaming the broken inventory.dat file on disk (as opposed to blindly removing it, which gives a change to analyze it). Pushed to 1.4 This bug was previously known as http://jira.rhq-project.org/browse/RHQ-1897 Temporarily adding the keyword "SubBug" so we can be sure we have accounted for all the bugs. keyword: new = Tracking + FutureFeature + SubBug making sure we're not missing any bugs in rhq_triage I know of no other time when someone reported this. Might be caused by an anomaly during perf testing using agentspawn (which is not a true production environment situation). We have a new inventory --sync mechanism that we can utilize to force the agent to resync its inventory (and this rebuild inventory.dat) in case it ever gets corrupted. Since no one has seen this again in over a year, I say close as "cannot reproduce". Closing this as WorksForMe. I wasn't able to with the latest rhq-server-4.0.0-SNAPSHOT build. If anyone see this. Please reopen. |
I have no idea what this means, if it is bad or not or if its recoverable. I saw it on an agentspawn deployment - many agents spit this out: 22:32:34,003 ERROR [Starting Agent 33007] (rhq.core.pc.inventory.InventoryManager)- Could not load inventory data from disk org.rhq.core.clientapi.agent.PluginContainerException: Cannot load inventory file: /root/baker/perf/perftest/spawn/data/33007/inventory.dat at org.rhq.core.pc.inventory.InventoryFile.loadInventory(InventoryFile.java:107) at org.rhq.core.pc.inventory.InventoryManager.loadFromDisk(InventoryManager.java:1191) at org.rhq.core.pc.inventory.InventoryManager.initialize(InventoryManager.java:184) at org.rhq.core.pc.PluginContainer.startContainerService(PluginContainer.java:329) at org.rhq.core.pc.PluginContainer.initialize(PluginContainer.java:232) at org.rhq.enterprise.agent.AgentMain.startPluginContainer(AgentMain.java:1726) at org.rhq.enterprise.agent.AgentMain.start(AgentMain.java:622) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at org.rhq.perftest.AgentSpawn$1.run(AgentSpawn.java:170) at java.lang.Thread.run(Thread.java:595) Caused by: java.lang.NullPointerException at org.rhq.core.clientapi.agent.metadata.PluginMetadataManager.getType(PluginMetadataManager.java:179) at org.rhq.core.pc.inventory.InventoryFile.connectTypes(InventoryFile.java:113) at org.rhq.core.pc.inventory.InventoryFile.loadInventory(InventoryFile.java:105) ... 12 more
