Hello, I see many strange errors.
(1) ApiProxy$ApplicationException: ApplicationError: 2: too much contention on these datastore entities. please try again. It should be converted to ConcurrentModificationException. (2) ApiProxy$ApplicationException: ApplicationError: 5: Unknown I set deadline( http://code.google.com/intl/en/appengine/docs/java/javadoc/com/google/appengine/api/datastore/DatastoreServiceConfig.html#deadline%28double%29 ). This exception can see when timed out. It should be converted to DatastoreTimeoutException or ApiProxy$ApiDeadlineExceededException, I think. Why I can see such internal errors? traces: ------------ NativeException (com.google.apphosting.api.ApiProxy$ApplicationException: ApplicationError: 2: too much contention on these datastore entities. please try again.): com/google/net/rpc/RpcStub.java:1025:in `runInContext' com/google/tracing/TraceContext.java:440:in `run' com/google/tracing/TraceContext.java:639:in `runInContext' com/google/tracing/TraceContext.java:318:in `runInInheritedContextNoUnref' com/google/tracing/TraceContext.java:310:in `runInInheritedContext' com/google/tracing/TraceContext.java:438:in `run' com/google/net/rpc/RpcStub.java:1046:in `rpcFinished' com/google/net/rpc/RPC.java:2044:in `internalFinish' com/google/net/rpc/impl/RpcNetChannel.java:2298:in `finishRpc' com/google/net/rpc/impl/RpcNetChannel.java:1240:in `messageReceived' com/google/net/rpc/impl/RpcConnection.java:319:in `parseMessages' com/google/net/rpc/impl/RpcConnection.java:290:in `dataReceived' com/google/net/async/Connection.java:474:in `handleReadEvent' com/google/net/async/EventDispatcher.java:831:in `processNetworkEvents' com/google/net/async/EventDispatcher.java:207:in `internalLoop' com/google/net/async/EventDispatcher.java:103:in `loop' com/google/net/async/GlobalEventRegistry.java:95:in `runLoop' com/google/net/async/LoopingEventDispatcher.java:378:in `run' config/initializers/global.rb:274:in `makeSyncCall' bundler_gems/jruby/1.8/gems/appengine-apis-0.0.13/lib/appengine-apis/datastore.rb:214:in `transaction' bundler_gems/jruby/1.8/gems/appengine-apis-0.0.13/lib/appengine-apis/datastore_types.rb:544:in `convert_exceptions' bundler_gems/jruby/1.8/gems/appengine-apis-0.0.13/lib/appengine-apis/datastore.rb:212:in `transaction' lib/tiny_ds.rb:35:in `tx' NativeException (com.google.apphosting.api.ApiProxy$ApplicationException: ApplicationError: 5: Unknown): com/google/net/rpc/RpcStub.java:1025:in `runInContext' com/google/tracing/TraceContext.java:440:in `run' com/google/tracing/TraceContext.java:639:in `runInContext' com/google/tracing/TraceContext.java:318:in `runInInheritedContextNoUnref' com/google/tracing/TraceContext.java:310:in `runInInheritedContext' com/google/tracing/TraceContext.java:438:in `run' com/google/net/rpc/RpcStub.java:1046:in `rpcFinished' com/google/net/rpc/RPC.java:2044:in `internalFinish' com/google/net/rpc/impl/RpcNetChannel.java:2298:in `finishRpc' com/google/net/rpc/impl/RpcNetChannel.java:1240:in `messageReceived' com/google/net/rpc/impl/RpcConnection.java:319:in `parseMessages' com/google/net/rpc/impl/RpcConnection.java:290:in `dataReceived' com/google/net/async/Connection.java:474:in `handleReadEvent' com/google/net/async/EventDispatcher.java:831:in `processNetworkEvents' com/google/net/async/EventDispatcher.java:207:in `internalLoop' com/google/net/async/EventDispatcher.java:103:in `loop' com/google/net/async/GlobalEventRegistry.java:95:in `runLoop' com/google/net/async/LoopingEventDispatcher.java:378:in `run' config/initializers/global.rb:274:in `makeSyncCall' bundler_gems/jruby/1.8/gems/appengine-apis-0.0.13/lib/appengine-apis/datastore.rb:119:in `put' bundler_gems/jruby/1.8/gems/appengine-apis-0.0.13/lib/appengine-apis/datastore_types.rb:544:in `convert_exceptions' bundler_gems/jruby/1.8/gems/appengine-apis-0.0.13/lib/appengine-apis/datastore.rb:117:in `put' lib/tiny_ds/low_ds.rb:74:in `save' lib/tiny_ds/base.rb:160:in `do_save' lib/tiny_ds/validations.rb:21:in `save!' -- takeru -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
