Submission on hold on arxiv I have recently submitted a paper to arXiv, but the arXiv moderators put my paper in status "on hold", because they have to make a decision on the right classification for the paper. 

To those who have experienced a similar situation, how long did it take before they made a decision and published the paper on the arXiv? I just want to have an idea of how long I will have to wait.
I had the same experience with arxiv and it took only 1-2 days after they change my paper track. However, they mentioned it may take up to several days. The arxiv helps says


  On Hold
  
  Your submission was identified by arXiv administrators or moderators
  as needing further attention.
  
  Submissions may be put on hold for a variety of reasons, ranging from
  questions about proper classification, pending moderator approval,
  presentation issues, copyrighted PDF, etc., to editorial concerns.
  Most of these do not require any further input from the submitter and
  will be dealt with in due course. arXiv urges submitters to be
  patient. Due to the large volume of submissions, it may take several
  days before a resolution is reached.
  
  Note that oversize submissions are automatically put on hold, and this
  is one particular circumstance in which submitters should follow up
  with arXiv administrators.
  
  Submissions in this status will not expire. Authors must not create a
  new submission with the same content when a pending submission is on
  hold.
  
  Please be sure to include the submission identifier of the form
  submit/NNNNNNN when contacting arXiv administrators.


wait for few more days and send them an email. They are quick in response.
