Crash codes

This section describes AIX® crash codes.

Note: Some systems might produce 4-digit codes. If the leftmost digit of a 4-digit code is 0, use the three rightmost digits.
The crash codes that follow are part of an 888 Type 102 message s(see MAP4240 888 error code on HMC LPAR virtual control panel). These crash codes are grouped into three categories:
  • Category 1 - Dump analysis is the appropriate first action in Problem Determination. Call the next level of support.
  • Category 2 - Dump analysis most likely will not aid in Problem Determination. Call the next level of support.
  • Category 3 - Both software and hardware support might be needed in Problem Determination. Call the next level of support.
Table 1. Category 1 crash progress code
Progress code Description/Action
300 Data storage interrupt from the processor.
32x Data storage interrupt because of an I/O exception from IOCC.
38x Data storage interrupt because of an I/O exception from SLA.
400 Instruction storage interrupt.
700 Program interrupt.
Table 2. Category 2 crash progress code
Progress code Description/Action
200 Machine check because of a memory bus error.
201 Machine check because of a memory timeout.
202 Machine check because of a memory card failure.
203 Machine check because of an out of range address.
204 Machine check because of an attempt to write to ROS.
205 Machine check because of an uncorrectable address parity.
206 Machine check because of an uncorrectable ECC error.
207 Machine check because of an unidentified error.
208 Machine check due to an L2 uncorrectable ECC.
500 External interrupt because of a scrub memory bus error.
501 External interrupt because of an unidentified error.
51x External interrupt because of a DMA memory bus error.
52x External interrupt because of an IOCC channel check.
53x External interrupt from an IOCC bus timeout; x represents the IOCC number.

558 There is not enough memory to continue the IPL.
600 AIX 4.3.3.3 and above: Alignment Interrupt.
605 AIX 4.3.3.3 and above: AIX has crashed because the Portability Assist Layer (PAL) for this machine type has detected a problem.
