Your system stores information about errors and failures in the error log. This information includes error identifiers, which the error logging facility uses to compile reports. Each unique error identifier is a 32-bit CRC hexadecimal code that determines which error record template the report uses.
The following categories of error identifiers are ordered alphabetically, reading left to right.
