This could be just new year workload. Or someone is running some new
scripts that are consuming LARGE amounts of CPU. The data shows nothing
strange in the CPU distribution between servers:

And from a linux perspective, looking at the cpu by application, oracle
is consuming quite a bit - but it really looks like someone is running
short perl scripts continuously that are consuming large amounts of
data. (*PROD is the group of linux servers making up production, so
this is across all servers) . The "init" bucket is a catchall for short
term (less than 1 minute) processes who's parent process is init. Thus
the high "children" use in INIT for production.

From a couple of days one of our Linux LPAR are continuously using 100% of two
cpu. We are on EC12 with z/VM SSI 6.2, two IFL's CPU's, 61440 MB of RAM, 4096
Extended RAM and the guest are running on SLES 11SP2. Do anyone has similar
problems or there is a kernel update for this issue.
