title: sonarqube 5.2 background tasks sometimes fail with no log
body: <p>It seems that over half of the time I try to execute analysis using Sonar Runner 2.4 on several different projects that the analysis completes successfully but the publish (via the background task) to SonarQube fails.  There is no log that I can find with relevant information on the SonarQube server for the failed tasks - at least I can't find any.  I am new to SonarQube.  The SonarQube 5.2 server is on Windows Server 2012 R2 using SQL Server 2012(SP1) database.</p>
