Hi
I am checking the hpsmh process in my server.
When I run the top command, it displays the following process (see below). As you can see there are many hpsmh processes

But when I run ps -ef it only displays the following few hpsmh process (please see attachment). Why is this so?

Shalom,

They are starting and not closing and cleaning up nicely.

You probably need a new version of hpsmh and a schedules system boot.

Try to put off threads in top command using "H" .....

Best Regards

Please listen to Steven's remark.

As for "top", macero is right, it as to do with threading.
If you want a decent visualisation of your threading trees I suggest installing "htop". It adds extra features over the normal top and you can use kill commands from within it which is quiet useful.

I understand now, so top command is showing threads which the ps command does not.
