Type Definition
Description contains system error messages used to determine how the system is functioning.

The errors file contains error and "log-msg" messages. See "log-msg".

The item-ids are nine-digit date-time stamps (four-digit date plus five-digit time) plus an alpha character for multiple creations within a second.  

The specific types of errors which generate messages are:  

1) System errors: illegal opcode, crossing frame limit, forward link zero, backward link zero, priv opcode, illegal frame reference, disk error, stack format error, overflow release error, gfe, index B-tree error.

2) "logoff" commands.

3) Errors from the TPS (test procedure suite) on the QA account.

The attributes for the "errors" file are:

23 gfe-fid       Contains four values:
                  1) frame id of the group with gfe,
                  2) address (in storage register format)
                     of the item in which gfe was detected,
                  3) forward link of the frame in which
                     gfe occured,
                  4) backward link of the same frame
24 gfe-file      The path name of the file in which gfe
                was found.

Disk Error
On D3/Unix, the error log for a disk error has the following format:

ee dd 0000 00 00 ffffffff xx

ee  Unix error code. (value of errno)
dd  Logical disk number, as defined in configuration file
ffffffff  Frame number, in hex
xx  Command: 00=read, 01=write

The other fields are unused. Depending on the implementation, some other information can be obtained from the Unix error log.
