*Orphan process* parent is not *1*

The orphan is not added to parent based on *session ID*
{code}
if (!pID.equals("1")) {
ProcessInfo pInfo = entry.getValue();
String ppid = pInfo.getPpid();
// If parent is init and process is not session leader,
// attach to sessionID
if (ppid.equals("1")) {
String sid = pInfo.getSessionId().toString();
if (!pID.equals(sid)) {
ppid = sid;
}
}
