Sometimes I get the following exception (it doesn't happen all the time, but rather frequently), does anyone have an idea what could cause this? I have tried to Google the error, but the results I get do not help me. I am running Mendix 6.6.0 in the standard Mendix cloud.   Oct 13 11:45:21.741 127.0.0.1 tr10000: ERROR - ActionManager: Exception in execution of monitored action '{"name":"Module.MicroflowName","type":"Microflow"}' (execution id: 9c621bb1-0a2a-4309-b24e-e20dc0a3fb69, execution type: CLIENT_ASYNC_MONITORED) Oct 13 11:45:21.749 127.0.0.1 tr10000: ERROR - ActionManager: (1/111) com.mendix.modules.microflowengine.MicroflowException: com.mendix.systemwideinterfaces.MendixRuntimeException: com.mendix.core.CoreRuntimeException: com.mendix.systemwideinterfaces.MendixRuntimeException: com.mendix.systemwideinterfaces.connectionbus.ConnectionBusException: An exception has occurred for the following request(s): Oct 13 11:45:21.749 127.0.0.1 tr10000: ERROR - ActionManager: (2/111) IdentifierGetRequest: Object types: [Module.Entity] Oct 13 11:45:21.750 127.0.0.1 tr10000: ERROR - ActionManager: (3/111) at Module.MicroflowName2 (RetrieveFromCache : 'Retrieve Entity by $Account/Association') Oct 13 11:45:21.750 127.0.0.1 tr10000: ERROR - ActionManager: (4/111) at Module.MicroflowName (SubMicroflow : 'MicroflowName2') Oct 13 11:45:21.750 127.0.0.1 tr10000: ERROR - ActionManager: (5/111) Oct 13 11:45:21.750 127.0.0.1 tr10000: ERROR - ActionManager: (6/111) Advanced stacktrace: Oct 13 11:45:21.750 127.0.0.1 tr10000: ERROR - ActionManager: (7/111) at com.mendix.modules.microflowengine.MicroflowUtil.processException(MicroflowUtil.java:143) Oct 13 11:45:21.750 127.0.0.1 tr10000: ERROR - ActionManager: (8/111) Oct 13 11:45:21.751 127.0.0.1 tr10000: ERROR - ActionManager: (9/111) Caused by: com.mendix.core.CoreRuntimeException: com.mendix.systemwideinterfaces.MendixRuntimeException: com.mendix.core.CoreRuntimeException: com.mendix.systemwideinterfaces.MendixRuntimeException: com.mendix.systemwideinterfaces.connectionbus.ConnectionBusException: An exception has occurred for the following request(s): Oct 13 11:45:21.751 127.0.0.1 tr10000: ERROR - ActionManager: (10/111) IdentifierGetRequest: Object types: [Module.Entity] Oct 13 11:45:21.751 127.0.0.1 tr10000: ERROR - ActionManager: (11/111) at com.mendix.core.actionmanagement.ActionManager.executeSync(ActionManager.java:178) Oct 13 11:45:21.751 127.0.0.1 tr10000: ERROR - ActionManager: (12/111) Oct 13 11:45:21.751 127.0.0.1 tr10000: ERROR - ActionManager: (13/111) Caused by: com.mendix.systemwideinterfaces.MendixRuntimeException: com.mendix.core.CoreRuntimeException: com.mendix.systemwideinterfaces.MendixRuntimeException: com.mendix.systemwideinterfaces.connectionbus.ConnectionBusException: An exception has occurred for the following request(s): Oct 13 11:45:21.751 127.0.0.1 tr10000: ERROR - ActionManager: (14/111) IdentifierGetRequest: Object types: [Module.Entity] Oct 13 11:45:21.752 127.0.0.1 tr10000: ERROR - ActionManager: (15/111) at com.mendix.util.classloading.Runner.doRunUsingClassLoaderOf(Runner.java:36) Oct 13 11:45:21.752 127.0.0.1 tr10000: ERROR - ActionManager: (16/111) Oct 13 11:45:21.752 127.0.0.1 tr10000: ERROR - ActionManager: (17/111) Caused by: com.mendix.core.CoreRuntimeException: com.mendix.systemwideinterfaces.MendixRuntimeException: com.mendix.systemwideinterfaces.connectionbus.ConnectionBusException: An exception has occurred for the following request(s): Oct 13 11:45:21.752 127.0.0.1 tr10000: ERROR - ActionManager: (18/111) IdentifierGetRequest: Object types: [Module.Entity] Oct 13 11:45:21.752 127.0.0.1 tr10000: ERROR - ActionManager: (19/111) at com.mendix.core.actionmanagement.ActionManager.executeSync(ActionManager.java:178) Oct 13 11:45:21.752 127.0.0.1 tr10000: ERROR - ActionManager: (20/111) Oct 13 11:45:21.752 127.0.0.1 tr10000: ERROR - ActionManager: (21/111) Caused by: com.mendix.systemwideinterfaces.MendixRuntimeException: com.mendix.systemwideinterfaces.connectionbus.ConnectionBusException: An exception has occurred for the following request(s): Oct 13 11:45:21.752 127.0.0.1 tr10000: ERROR - ActionManager: (22/111) IdentifierGetRequest: Object types: [Module.Entity] Oct 13 11:45:21.753 127.0.0.1 tr10000: ERROR - ActionManager: (23/111) at com.mendix.util.classloading.Runner.doRunUsingClassLoaderOf(Runner.java:36) Oct 13 11:45:21.753 127.0.0.1 tr10000: ERROR - ActionManager: (24/111) Oct 13 11:45:21.753 127.0.0.1 tr10000: ERROR - ActionManager: (25/111) Caused by: com.mendix.systemwideinterfaces.connectionbus.ConnectionBusException: An exception has occurred for the following request(s): Oct 13 11:45:21.753 127.0.0.1 tr10000: ERROR - ActionManager: (26/111) IdentifierGetRequest: Object types: [Module.Entity] Oct 13 11:45:21.753 127.0.0.1 tr10000: ERROR - ActionManager: (27/111) at com.mendix.connectionbus.RequestAnalyzer.doRequest(RequestAnalyzer.java:46) Oct 13 11:45:21.753 127.0.0.1 tr10000: ERROR - ActionManager: (28/111) Oct 13 11:45:21.753 127.0.0.1 tr10000: ERROR - ActionManager: (29/111) Caused by: com.mendix.systemwideinterfaces.connectionbus.ConnectionBusException: Exception occurred while retrieving data.
