How do I troubleshoot a multi-bit memory error?

When troubleshooting a multi-bit memory error you are trying to determine if it is a memory module, slot, or memory controller issue. The memory controller is on the CPU. On 11th generation and older servers the memory logs must be manually cleared. If you don’t clear the memory logs then you may have false errors reported.

What does error 6545 1404 – instrumentation service status is critical?

Server_Administrator: 6545 1404 – Instrumentation Service Memory device status is critical #012Memory device location: DIMM_B3 #012Possible memory module event cause:Multi bit error encountered The memory is configured as follows: I swapped B1 and B3 to see if the error moved.

How to clear single bit warning error rate exceeded on Linux?

Similarly, I was seeing “Single bit warning error rate exceeded” and “Single bit failure error rate exceeded” on a Linux host. These can be cleared as well but with omconfig: ‘omconfig system alertlog action=clear’ and ‘omconfig system esmlog action=clear’. Lets hope they don’t come back or its trash for the dimms.

Why can’t the system read from the specified device?

The system cannot read from the specified device. A device attached to the system is not functioning. The process cannot access the file because it is being used by another process. The process cannot access the file because another process has locked a portion of the file. The wrong disk is in the drive.

What happens when multiple bit errors are detected?

By default, if a multiple-bit error is detected, a nonmaskable interrupt (NMI) is generated to interrupt the Routing Engine and panic the kernel causing the router to subsequently reboot. The Routing Engine panics the kernel, and leaves a vmcore file.

What are the different types of memory errors?

There are two types of memory errors: single-bit and multiple-bit. A single-bit error is when a single 0 or 1 bit is incorrect. The system detects and corrects single-bit errors, then logs the event in the /var/log/eccd file. If there are persistent single-bit errors, the Routing Engine controller reboots the Routing Engine.

What is a single-bit error?

A single-bit error is when a single 0 or 1 bit is incorrect. The system detects and corrects single-bit errors, then logs the event in the /var/log/eccd file. If there are persistent single-bit errors, the Routing Engine controller reboots the Routing Engine. Persistent single-bit errors could be a symptom of bad RAM.
