command:
./check_hpasm -H hostname -C public -v
output:
check_hpasm timed out after 60 seconds

After reading around it seems like many others have had this same issue with this plugin. From what I gathered, it might be related to time out and HP taking time to process during high load times.

Can you run the command with the -v -t 120 flags and post the output here?

Try a few times to see if it fails the first time. When you mentioned that it sometimes works, and sometimes does not that is the first thing that comes to mind.

Dear rkennedy :
thanks your reply,
I used the command with -v -t 120 , I found some servers hardware status is work fine, you're right,
and have other servers hardware status still failed and timeout , I changed -t 180 ,it also have same error.

Hmm, so did it fix some and not others?

Are these servers at a remote location?

I still believe it is the timeout, perhaps with a -t 240 or -t 300 that will be enough time for a response?
