copy with PSEXEC hangs some times in batch execution

Question

im copying multiple files to server Machine using PSEXEC,Calling Psexec is through perl file

my $exit_code5 = system("cmd /c c:\\PsExec.exe \\\\$host_name  -u  $user_name  -p \ $pwd  cmd /c xcopy \"\\\\$client\\c\$\\sif folder\\$val\" \"c:\\sif folder\\\" /O /X /E /H /K /Y /q");
sleep(20);

}
if($exit_code5!=0)
{
}

This command is working fine , but sometimes in batch executions it randomly fails

Try adding -d in your command since it doesn't wait for the process to terminate https://technet.microsoft.com/en-us/sysinternals/bb897553.aspx
