I used some forking code to take care of a similar situation like this

foreach my $market (@HOSTLIST) {
   if( my $mypid = fork() ) {
      print("$market is pid $mypid\n");
   } elsif( $mypid == 0 ) {
      new_session($market);
   } elsif( ! defined $mypid ) {
     die "Error: Couldn't fork: $!";
   }

Mix it in with a procedure to sleep five minutes and try again for failed attempts and a max number of 3 retries.
