Can you attach a ps output that shows these zombies and init:
UNIX95=EXTENDED_PS ps -ef -H

If your process is unkillable and hang, it is probably looping in the kernel.
In that case the best to do is to take a TOC and contact HP support.

If it is killable, then you can attach a tusc
to try to understand what's happening.

And in any case contact HP support

Yes, you need to contact HP and ask for them to collect the kitrace logs from the server.
