EZZ9893I

Explanation
 The setgroups() API failed to drop the privileges
of sendmail tasks. sendmail does not have permission to change to
the new group ID. For example, a return code of 157 and a reason code
of 0BD602A4 indicate EMVSERR (157) and JRMultiproc (02A4). This means
that the specified function does not support running multiple processes.
In this case, ensure that the environment variable _BPX_SHAREAS is
set to NO (export _BPX_SHAREAS=NO).
 empty_group_id is
the group ID to which sendmail is to be set. 
 returncode is
the z/OS® UNIX System Services return code returned from
the setgroups() API. These return codes are listed and described in z/OS UNIX System Services Messages and Codes. 
 reasoncode is
the hexadecimal z/OS UNIX System Services reason code
returned from the setgroups() API. The format of the 4-byte reason
code is explained in the introduction to the Reason Code section of z/OS UNIX System Services Messages and Codes, where these reason codes are listed. 
 description is
a description of the error.

System action

Operator response
 Contact the system programmer.

System programmer response
 Update the configuration file to
set RunAsUser to a user ID that sendmail has permission to change.
Use returncode and reasoncode to
determine the cause of the error. See z/OS XL C/C++ Runtime Library Reference for more information about the setgroups()
API.
