-- Tatham -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Tatham Oddie Sent: Friday, 12 August 2011 3:57 PM To: Neo4j user discussions ([email protected]) Subject: [Neo4j] java.lang.OutOfMemoryError: PermGen space Howdy, We've started experiencing reasonably consistent java.lang.OutOfMemoryError exceptions. We're using neo4j-community-1.4.M04-windows.zip, running on Windows 7 x64 for development + Windows Azure for production. Graph access is exclusively via REST. We perform basic CRUD operations and Gremlin queries. The server spins up like so: 12/08/11 2:39:43 PM org.neo4j.server.NeoServerWithEmbeddedWebServer INFO: Starting Neo Server on port [5102] with [80] threads available 12/08/11 2:39:43 PM org.neo4j.server.database.Database INFO: Using database at C:\AzureTemp\neo4j-db 12/08/11 2:39:47 PM org.neo4j.server.modules.DiscoveryModule INFO: Mounted discovery module at [/] 12/08/11 2:39:48 PM org.neo4j.server.plugins.PluginManager INFO: Loaded server plugin "CypherPlugin" 12/08/11 2:39:48 PM org.neo4j.server.plugins.PluginManager INFO: Loaded server plugin "GremlinPlugin" 12/08/11 2:39:48 PM org.neo4j.server.modules.RESTApiModule INFO: Mounted REST API at [/db/data/] 12/08/11 2:39:48 PM org.neo4j.server.modules.ManagementApiModule INFO: Mounted management API at [/db/manage/] 12/08/11 2:39:48 PM org.neo4j.server.modules.WebAdminModule INFO: Mounted webadmin at [/webadmin] 12/08/11 2:39:48 PM org.neo4j.server.web.Jetty6WebServer INFO: Mounting static content at [/webadmin] from [webadmin-html] 12/08/11 2:39:50 PM org.neo4j.server.NeoServerWithEmbeddedWebServer INFO: Server started on [http://192.168.10.151:5102/] Then, after a relatively small number of queries (sub 500? still confirming more details), we get this: Exception in thread "RMI RenewClean-[192.168.10.151:31174]" java.lang.OutOfMemoryError: PermGen space Exception in thread "Statistics Gatherer" java.lang.OutOfMemoryError: PermGen space Java.exe is still running, and consuming around 180MB of RAM (with another 3GB of physical memory still available on the system). REST API returns 500s and the WebAdmin is unavailable. My questions: 1) Is this just that we've got a configuration setting wrong? In my very limited knowledge of Java, I know we can reconfigure the size, but this seems to indicate a potentially larger issue. 2) What should I do to gather more information to help diagnose this? -- Tatham Oddie au mob: +61 414 275 989, us cell: +1 415 598 8201, skype: tathamoddie If you're printing this email, you're doing it wrong.
