1911872 - Missing errorlog message about "Number of proc buffers allocated" in ASE 12.5 and later versions

Symptom

The "Number of proc buffers allocated" message mentioned in the "System Administration Guide" no longer appears in the errorlogs of newer versions of Adaptive Server Enterprise.

ASE 15.7 ESD #2 System Administration Guide Volume 2 says :

"------------------------------------
Adaptive Server Enterprise 15.7 ESD #2
- System Administration Guide: Volume 2
   - Configuring Memory
     - Configuration parameters that control Adaptive Server memory
       - Data and procedure caches
------------------------------------

Procedure cache messages

  These error log messages provide information about the procedure cache:

    server: Number of proc buffers allocated: 556
    server: Number of blocks left for proc headers: 629
------------------------------------"


But in ASE 12.5.x and later, the message "Number of proc buffers allocated: xxxx" no longer appears.
Only the "Number of blocks left for proc headers: xxxxx" message remains.

For examples of the messages that appear in the errorlog of various ASE versions, see below.

What happened to this message? How can I get information about memory usage in the procedure cache?
