Which is the original SP2 kernel shipped in Feb 2012 so no updates have ever been applied since installation. It also goes out of support in 3 weeks.
Hard to say if it is a kernel bug, but there have been about 15 new SP2 kernels since that one. PS. We still can't get to SP3 due the swap thing I posted about in November, so I would suggest getting to latest SP2 maintenance (which you'd want to do before install SP3 anyway) Marcy -----Original Message----- From: Linux on 390 Port [mailto:LINUX-390@VM.MARIST.EDU] On Behalf Of Victor Echavarry Diaz Sent: Friday, January 10, 2014 10:08 AM To: LINUX-390@VM.MARIST.EDU Subject: Re: [LINUX-390] High cpu utilization on vm/linux LPAR Those are oracle guests.

In a prior life, I was in the VM and Linux team supporting apps mostly WAS based. We saw a lot of "mysterious" loads. While IBM has made improvements in WAS, the apps are always in need of review. The most common (and extreme) example is apps which poll. Not so much a concern on an otherwise idle PC, this is a gross CPU waste in any shared environment, virtual or not. Look for things like that. But that's just one example. -- R; <>< On Jan 10, 2014 11:04 AM, "Victor Echavarry" <vechava...@evertecinc.com> wrote: > From a couple of days one of our Linux LPAR are continuously using 100% of > two cpu.
