To answer also the question of Adrian Klaver:
The database in question has ~400 tables and the ESQL/C application has
for each table its own ESQL/C source file. It would be possible but a
nightmare to share the code and it's better to discuss the problem based
on the ESQL/c log file or I have to write some small example code to
reproduce the problem. The line numbers are relative to those source
files (and it's a pitty that the name of the source file is not logged,
onle the line numbers).
Yeah, but there is a one:one mapping of table:source file and you know
the table, so you should be able to find the source at the line number.
Or am I missing something?
Also, from OP did:
insert into swd_auftrag ..
COMMIT?

Kind of hard to believe ... is there any sign of distress in the

No. Nothing which points to this.
I have here the ESQL/C
logging of the problem:
...
[1471] [12.05.2020 15:48:50:476]: ecpg_execute on line 1744: query: insert into swd_daten ( katkey , aktion , reserv , id , ansetzung , nettodaten ) values ( $1 , $2 , $3 , $4 , $5 , $6 ); with 6 parameter(s) on connection sisis
[1471] [12.05.2020 15:48:50:476]: ecpg_process_output on line 1744: OK: INSERT 0 1
[1471] [12.05.2020 15:48:50:477]: ECPGtrans on line 6716: action "commit"; connection "sisis"
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
It's striking that this log shows a server ack of the INSERT, but no server
ack of the COMMIT. Maybe that's just an oversight in the ESQL/C logging
logic, but I wonder what's actually getting to the server. You might try
I looked into the source and the ECPGtrans ... is logged before its
execution in the source interfaces/ecpg/ecpglib/misc.c and after the
execution only an error condition would be logged. As there is only the
line of the COMMIT w/o anything else, it seems to be executed fine.
enabling log_statement = all so you can get a trace of what the server
thinks is happening.
I will do so, but would have to find a time window for this to not be
swamped by the logs.
Thanks for your reply to both, Adiran and Tom.
