dev_w0 errors

[Former Member]

Hi All,

This error keeps showing up in my dev_w0 file. It only appears in the Workprocess 0, teh first one. Atleast one job which ftp's a file to the server is failing because of this. The jobs dumps with DATASET_CANT_CLOSE, exception CX_SY_FILE_CLOSE. It says that it could not close a temp.txt file because it coudnt get enough memory.

This should not be a memory problem because we have an identical system on the same machine with exact same parameters, and it works in there.

I even installed the latest Kernel Patch, but it didnt help.

This is a ECC6 system on AIX/Oracle 10.2.0.2.

Dear Cyrus,

this simply means that the child process that was created by the work process did not exist anymore when the work process tried to determine its exit status. This can be the case if the OS does not keep a zombie process until the parent process collects the exit status of the child process. You can try the profile parameter

sig/default = <SIGCHLD>

(where <SIGCHLD> is the number associated to SIGCHLD which can be determined by running kill -l and then counting the entries starting from 1) to attempt to force the OS to keep the child process alive long enough. You might also want to check

Hi,

I am a not an ABAP developer, so i didnt understand a whole lot of the document.

I am looking at this from Basis point of view. What might be causing these errors to appear in the trace files. I couldnt find any notes in SAP for this error.

Does anyone know what might be happening in the background that might be causing these errors?
