sg_spol vmunix: LPMC type : I-Cache Parity Error

sg_spol vmunix: LPMC type : I-Cache Parity Error ???

Which the level of gravity of two errors generated for this problem!

Debtor!

Re: sg_spol vmunix: LPMC type : I-Cache Parity Error

Hi Cesar,

LPMC => Low Priority Machine Check
I-Cache Parity Error => Instruction cache errors on the CPU

If you have one or two of these errors a week you should not worry. If you have more errors its time to call HP. Have a look at next discussion for more info.

Re: sg_spol vmunix: LPMC type : I-Cache Parity Error

I-cache errors are Instruction cache errors. The Instruction cache is
the area on the CPU where instructions sets of frequently run code are loaded
from main memory for easier, quicker access. I-cache errors occur when there
is a problem pulling an instruction, or set of instructions, from this cache
memory. This invariably points to a CPU issue (CPU probably needs
replacement).

Usually, one or two errors are not a problem - it usually indicates that at
that particular time an instruction, or set of instructions, was/were not
successfully accessed. But if there are many errors, it could be due to other
factors such as power surges, hardware failure, or system environment. If you
are getting many errors, it should be looked at and corrected, as it can lead
to a High Priority Machine Check (HPMC) and a possible system halt/panic.

Since this error is most likely due to a CPU failure, and to avoid a possible
system halt, please contact the Hardware Support Team so they can
schedule a Customer Engineer (CE) visit to replace the CPU.
Time has a wonderful way of weeding out the trivial

Re: sg_spol vmunix: LPMC type : I-Cache Parity Error

Refer to /var/tombstones/ts##, ie., ts99, for LPMC's and HPMC's. HPMC's (* high priority machine check *) can't be ignored and should prompt your immeidate attention. Follow Mr. Gossens advice about LPMC's.
