Sorry, I forgot to mention that, in my case, Windoz and Linux ran fine on the server, yet Solaris 10 would panic on boot.
I replaced the SCSI cable and haven't seen the panic since. -----Original Message----- From: [email protected] [mailto:ug-msosug-bounces at opensolaris.org] On Behalf Of Blakeman, Murray J Sent: Wednesday, 3 June 2009 10:05 AM To: Chris Wells; Melbourne OpenSolaris Users Group Subject: Re: [ug-msosug] Help wanted : Stress test required in LiveCD I had similar issues quite while ago with a Solaris 10 install and I narrowed it down to a bad SCSI cable. -----Original Message----- From: [email protected] [mailto:ug-msosug-bounces at opensolaris.org] On Behalf Of Chris Wells Sent: Wednesday, 3 June 2009 9:37 AM To: Melbourne OpenSolaris Users Group Subject: [ug-msosug] Help wanted : Stress test required in LiveCD Hi All - I need to use the MSOSUG hive mind! I've got a newly built system (OpenSolaris 2009.06 / nv111b) which is unpredictably panicking, and I want to narrow down why this is happening. I've seen it mainly happening when the system is under higher IO load (eg when doing a "zfs scrub rpool"). I have got quite a few (15!) crashdumps, and have looked at the function stacks, and there doesn't seem to be any consistent pattern. Sun (God bless em!) have said that they've seen a single-bit flip in one of the crashdumps, and are wondering if it's hardware related issue. (The memory is non-ECC). I've already run memtest86 (which completed 13 iterations without finding fault), and am wondering on the next steps. I was wondering how to subdivide the problem - my initial thoughts are to: 1) Remove the harddisks, and boot from the LiveCD - and then run some memory and CPU stress tests - Can anyone suggest a suitable stress test that could be run from the LiveCD (ideally in text / singleuser mode)? 2) Exchange the harddisks with some spares, and reinstall OS2009.06 (or another OS) from scratch.
