Sharon,
now I performed the proposed test. While under STAF/STAX the problem shows up in
about 30% of the tests, I could not recreate the problem starting the process
manually.
I did not change anything of the parameters of the process. As it wants to
write to
STAXMon, I started my normal STAXJob using the "HOLD" option and gave the JobID
to the process, as normally is done by my STAX script.
So, the only difference should be using STAF/STAX or not.
Bodo

Hi Bodo,
There are no known problems.
If you run your process without using STAF/STAX and redirect its stdout and
stderr to the same file do you ever see this problem occur? For example:
# yourprogram > /tmp/process.out 2>&1
If so, then it wouldn't appear to be a problem in STAF/STAX.
If this problem doesn't occur when you run the program without STAF/STAX, If
you change your <process> element to redirect stdout and stderr to two
different files by using the <stderr> element and specifying a file name and
not specifying mode="'stdout'", does the problem no longer occur? e.g. Does
the stderr file always contain the first line you expect to be written to it?

[staf-users] Sporadically first line of stderr missing
Hi,
my STAXJob starts a <process>. The process writes to stdout and stderr quite
simultaneously, as it forks and one writes to stdout and the other writes to
stderr
both using fputs().
All output lines also are printed to STAXMon using 'STAX JOB nn MESSAGE'
STAFF shall write both, stdout and stderr to one file, as the <process> element
contains a <stdout>filename</stdout> and a <stderr mode="'stdout'"/>.
On STAXMon, all output messages are present. But on the file, sometimes the
first line of stderr is missing. All others always are present.
Is there any known problem?
Best Regards
