Subject Re: Exception in the running Custom Job

Hi Nikita,

Until you fix your connector, nothing can be done to address your Out Of
Memory problem.

The problem is that you are not calling the following IProcessActivity
method:

  /** Check whether a document of a specific length is indexable by the
currently specified output connector.
  *@param length is the document length.
  *@return true if the document is indexable.
  */
  public boolean checkLengthIndexable(long length)
    throws ManifoldCFException, ServiceInterruption;

Your connector should call this and honor the response.

Thanks,
Karl
