Timer Job Fires Multiple Times

This happens because the way you call your timer job constructor. You should use SPJobLockType.Job NOT SPJobLockType.ContentDatabase.  Constructor Code should look like the following

Keywords: SharePoint, SharePoint 2010, SharePoint 2013, Timer Jobs

public ConventusMDToAXTimerJob(): base()

{

}

public ConventusMDToAXTimerJob(string jobName, SPWebApplication webApplication)

:base(jobName, webApplication, null, SPJobLockType.Job)

{

    this.Title = JOB_NAME;

}

Problem solved. Enjoy
