I'm using perl5.6.1 and am trying to debug a program that creates a background process via a system call. The following is the affected code. 

   if ( $pid eq "" )          # if null, MEVS not running - issue comm
+and to start MEVS
   {
       @command = ("/mevs/$version/bin/mevs", "/mevs/$version/data/con
+fig_data/mevs2.cfg", "online");
       system(@command, "&");                     # restart MEVS

       $pid = get_pid($version);  # Get the current $version mevs pid

        chomp $pid;       # chomp if not null
        print STATUSLOG "\n\n$ctime [$pid] -- MEVS Status Log -- The M
+EVS Online process has been restarted\n\n";

The problem is that the debugger goes into a wait state for a response as the following shows: 
  DB<1> b 151
  DB<2> c
MEVS 2.0, Medicaid Eligibility Verification Server, (c)2003.
Done.


12/07/04 @ 11:13:41 : MEVS started in Online mode, on port 6500, with 
+20 listening slots.

I no longer get any DB<> prompts. It seems it just hangs. I know I created a background process because I can kill the perl process and the MEVS system is still running.
