PROCESS_LAUNCH_ Procedure
10 Unable to communicate with system-monitor process; error-detail contains a 
file-system error number*.
11 Process-name error; error-detail contains a file-system error number*. File-
system error 44 indicates that, when trying to create a named process, either the 
DCT is full or there are no system-generated names available.
12 Invalid program-file format; error-detail subcodes are described in 
Table 12-5, Error Subcodes for Process Creation Errors 12, 13, 70, 76, 84, and 
3xx.
13 Invalid user-library-file format; error-detail subcodes are described in 
Table 12-5, Error Subcodes for Process Creation Errors 12, 13, 70, 76, 84, and 
3xx.
14 The process has undefined externals, but was started anyway (this is a warning). 
15 No process control block available, or no PIN less than 255 is available.
16 Unable to allocate virtual address space.
17 Unlicensed privileged program or library.
18 Library conflict (see “General Considerations”).
19 Program file and library file specified are same file.
20 Program file has an illegal process device subtype. (See “General 
Considerations.”)
21 Process device subtype specified in backup process is not the same as that in the 
primary process.
22 Backup creation was specified, but caller is unnamed.
24 DEFINE error; error-detail contains either a file-system error number, a 
DEFINE error number*, or the following error subcode.
2 An excessive number of DEFINEs were to be propagated. See “DEFINE 
Considerations.”
26 Dynamic IOP error. (This error is returned only to privileged callers or to 
unprivileged callers attempting to use certain privileged features. On D-series 
RVUs, it can be returned when an I/O process is incorrectly configured. On G-
series RVUs, it can be returned by an attempt to create a D-series I/O process.)
27 PFS size in program file is invalid (this error is not generated in G06.12 and later 
RVUs).
28 An unrecognized error number was returned from a remote system (probably 
running another level of software); error-detail contains the error number.

error  Description
* Refer to the Guardian Procedure Errors and Messages Manual for a list of all file-system and DEFINE errors.
**When error-detail indicates the number of a shared run-time library (SRL), the number represents either 
the public SRL relative number, or 00 for a native user library. For more information on shared run-time libraries 
(SRLs) refer to the nld and noft Manual.
Note: Refer to Guardian Procedure Errors and Messages Manual for Cause, Effect, and Recovery of all the 
Process Creation Errors.
