syslog errors

[Joe White]

I'm getting the following syslog errors;
vmunix: Detected Low Priority Machine Check
vmunix: LPMC Type : (ECC-corrected single-bit error
vmunix: Error Address : 0x1b7b7d8
Suspecting a possible hardware failure I ran
ioscan -fn. The EISA card showed up as 'unknown and in a S/W state of ERROR. Is there a way to see if the error address in syslog matches the EISA card error?

Joe,
LPMC's are hardware errors. They are cousins to HPMC or High Priority errors which can crash the system. I have seen LPMC's crash a machine but that is usually not the norm.

Call your Hardware support and report these errors.

Joe,

These two messages are not related. The LPMC single-bit memory errors are not necessarily a problem unless you get a lot of them. They mean that a single bit error in memory has been detected and corrected by the system. This can be caused by a hardware error in memory but the occasional event can be caused by stray background radiation.

The EISA card that you listed with ioscan looks as though it may not have the related driver software installed and configured. What sort of card is it?

[Rick Garland]

LPMC errors can be either sporadic or numerous in frequency. In either case, if you have DIAGS loaded and can access the stm (cstm, xstm, or mstm) you can determine which piece of HW is causing the LPMCs. If they become numerous and frequent, call HP for HW support.

Hello Joe

LPMC is not critical problem. It is normally corrected by system. But continuity of LPMC can make a system crash.
In my view, an ECC-corrected single-bit error is related to memory.
I'd like to recommend you call your H/W support.

An ECC error is definitely memory related. A single error is not a significant problem, but if it happens repeatedly it's time to get some memory replaced. In the meantime, LPMC errors are broadcast to all connected users, so your phone could get busy. The EISA problem that you noted is unrelated to this memory issue, but certainly worth further investigation.
