title: nohup Command Not Completing The Job
body: <p>I am using Debian Linux 64Bit 4Gb RAM 2 CPU VPS Server.
  I am executing 50 PHP files using 50 nohup commands and saving their logs.
  I watched that all the given jobs not fully completing. Its stopped at 30% sometimes 50% sometimes at 90%.
  Previously I thought its happening due to less RAM. then I checked the RAM, only 1gb used. 3gb free RAM.
  So I am definitely sure that its not happening due to less RAM.</p>
  
  <p>So whats wrong ?
  Why my given jobs not fully completing ?
  When I use manually it's working fine. Taking 30 minutes.
  But in nohup its stopped at 30%,40%,60%.</p>
  
  <p>Please help. How can I solve the problems. 
  Thank you.</p>
