IBM can't tell more than what they see in the snaps etc. from the OS gathered by perfpmr. Since they didn't see anything strange, they ask for the application as they can't have a clue how the application works, that's right.

Are you sure it didn't look the same before the upgrade? Question might sound stupid, but just to make sure.
High C shows them currently active but the percentage is average since start so can you talk with any of the users and ask what they are doing or if they are doing different things than usual (at least jufackle?). Sometimes there is a perdiodic run of other tasks because of business things like gathering end-of-the-month statistics or whatever could be the reason to produce a peak - you'd better know or maybe your users than I.
Is the box being pressed against the wall vmstat-wise?

Killing or stopping the application by one user and starting anew will have the same effect that C rises up that high immediately?

You could check (awful work) what enhancements or fixes the difference between 5300-06-03 and 5300-12-04 has brought.

Sorry to have no better idea at the moment to help you.

Do you have nmon-monitoring up maybe to check pre-update data with current cpu/process wise? If not it could be helpful in the future.

PAM_ISSUE(8)							 Linux-PAM Manual						      PAM_ISSUE(8)

NAME

       pam_issue - PAM module to add issue file to user prompt

SYNOPSIS

       pam_issue.so [noesc] [issue=issue-file-name]

DESCRIPTION

       pam_issue is a PAM module to prepend an issue file to the username prompt. It also by default parses escape codes in the issue file similar
       to some common getty's (using x format).

       Recognized escapes:

       d
	   current day

       l
	   name of this tty

       m
	   machine architecture (uname -m)

       

	   machine's network node hostname (uname -n)

       o
	   domain name of this system

       
	   release number of operating system (uname -r)

       	
	   current time

       s
	   operating system name (uname -s)

       u
	   number of users currently logged in

       U
	   same as u except it is suffixed with "user" or "users" (eg. "1 user" or "10 users")

       v
	   operating system version and build date (uname -v)

OPTIONS

       noesc
	   Turns off escape code parsing.

       issue=issue-file-name
	   The file to output if not using the default.

MODULE TYPES PROVIDED

       Only the auth module type is provided.

RETURN VALUES

       PAM_BUF_ERR
	   Memory buffer error.

       PAM_IGNORE
	   The prompt was already changed.

       PAM_SERVICE_ERR
	   A service module error occurred.

       PAM_SUCCESS
	   The new prompt was set successfully.

EXAMPLES

       Add the following line to /etc/pam.d/login to set the user specific issue at login:

		   auth optional pam_issue.so issue=/etc/issue

SEE ALSO

       pam.conf(5), pam.d(5), pam(7)
