>From imspecting the code there appears to be a race condition if two threads >call LoggingEvent.LookupProperty concurrently. One thread may call >CreateCompositeProperties and the other might access m_compositeProperties >before it is fully created. public object LookupProperty(string key) { if (m_data.Properties != null) { return m_data.Properties[key]; } if (m_compositeProperties == null) { CreateCompositeProperties(); } return m_compositeProperties[key]; } private void CreateCompositeProperties() { m_compositeProperties = new CompositeProperties(); if (m_eventProperties != null) { m_compositeProperties.Add(m_eventProperties); } ... etc -- This message was sent by Atlassian JIRA (v6.3.4#6332)
