Re: System unreachable
I can remember several issues with v1 and vhand (which were fixed with patches). I don't tend to rely on memory stats from "top", it's a shame you don't have glance installed. It's difficult for me to see the RSS figures for your SAP processes (it looks like 30Gb - but that may be shared memory).
I'd definitely consider making SWAP 1.5x RAM (at least).
Now, I wonder if they still have the evaluation copy of Glance somewhere.........

Re: System unreachable
You have messages being sent an nothing listening, that is, if your firmware is up to date. IF not, then you have nothing being sent and nothing listening.

Re: System unreachable
If you want to know why a system was hung, you need to use TC to get a memory dump. (You first need to make sure crash dumps are enabled.)
>swapinfo -t
(It would helpful next time to always use -tam.)
>Patrick: A ping indicates some modicum of network connectivity, but that's no guarantee that other things will work.
I've had that too, unfortunately. :-(
>Keith: as HP-UX wants to reserve the same amount of RAM in swap at all times.
As long as you have pseudo-swap enabled, that's a myth about device swap.

Re: System unreachable
Question for you: Has your application been upgraded recently with any new rollouts?
I ask because a memory leak could freeze the system.
Let me know.
Anyway, you're not going to know where the problem is until you upgrade your diags and firmware. You're probably many, many version out of date.

Re: System unreachable
Not sure about the rollouts.. i know they did a database refresh a few months back.. but this is their app server, so not sure what changes were made on it.. but i will ask. In the meantime, I will take your suggestion and see what I can do to expedite the patch/firmware and diag update..
Thanks for your feedback.
