Issue/Introduction
When exploring log files, we found the following message:
20210910/020052.101 - 37 U00009907 Memory dump '(BINDPAR: 1)' (Address='n/a', Length='000004')

Is there a way to explain the "Memory dump" message?
Cause
This a normal message that can be ignored. It is displayed when a Time Critical DB call longer than 2 seconds is reporting which bind parameters where used.
You will see that each time "U00009907 Memory dump '(BINDPAR: %n)' is followed by a bind parameter 2 lines below between >%b<
The fact that it mentions "Memory dump" is confusing but there is no Forced Trace.
Environment
Release : 12.3
Component : JWP / JCP
Resolution
The following message structure in the JWP/JCP logs should be ignored:
U00009907 Memory dump '(BINDPAR: %n)'
There is NO memory dump, the JWP/JCP is only reporting the bind parameters of Time Critical DB call.
In the example below a bind parameters (1078186886) is passed for the parameter AUSR_AH_Idnr. This is particular for the Time Critical calls in Java processes.
