title: Is Interop.Domino dll thread safe?
body: <p>I am using Interop.Domino dll version 1.2 in c# application, and using multithreading to access multiple NSF file at same time by creating new session for each thread created (Max 5 threads at a time).</p>
  
  <p>For the large NSF files, I was getting the Notes error like memory segment overflow.
   To overcome this problem, i used Marshal.ReleaseComObject(object) to release the necessary Notesdocument, and NotesView object where ever possible.</p>
  
  <p>Now, the issues is like, i am able to access 2 NSF files but the rest threads are going in dll exceptions as few Notes object are getting null.</p>
  
  <p>Kindly provide me some help....</p>
  
  <p>Thanks for help.</p>
