SAPFTP 46D_EXT2 on SAP 4.6C not transferring all files

Hi experts,

I have a rare issue in using sapftp on 4.6D EXT2 release used by a SAP 4.6C system non-unicode.

Database is Oracle 10.2.0.5 and OS is Linux SLES 11 SP1.

The problem with this is that when I am using this sapftp to connect to other servers and transferring files, not all transfers are

successful. I am getting a segfault error or connection error for some of the transfers that are not successful.

The amount of files transferred will not matter whether it may be 10 documents, 100 documents, or 500 documents. The transfer will fail for some but will proceed with the others randomly.

The sapftp version is:

./sapftp -V

SAPFTP Non-Unicode

@(#) $Id: //bas/46D/src/krn/ftp/ftpmain.c#32 $ SAP

@(#) $Id: //bas/46D/src/krn/ftp/ftp.c#26 $ SAP

@(#) $Id: //bas/46D/src/krn/ftp/ftpcmd.c#23 $ SAP

SAP release: 46D SAP release no: 4640

However, when we make use of sapftp of a higher release, in particular 720_EXT.

SAPFTP Non-Unicode

@(#) $Id: //bas/720_REL/src/krn/ftp/ftpmain.c#13 $ SAP

@(#) $Id: //bas/720_REL/src/krn/ftp/ftp.c#2 $ SAP

@(#) $Id: //bas/720_REL/src/krn/ftp/ftpcmd.c#4 $ SAP

SAP release: 720 SAP release no: 7200

The issue no longer exists and that all file transfers becomes successful.

Please note that we have enabled sapftp.ini to enable passive mode by default.

When checking the OS logs as well in /var/logs/messages we can see some

notable memory issues in sapftp when using kernel 46D of sapftp.

For both sapftp release on 46D_EXT2 and 720_EXT, we tested sample

connections using RSFTP002 and RSFTP003 and both are successfully

tested. Just that when transferring many files, the sapftp of kernel

46D_EXT2 fails at some point and not all files are being transferred as

a result.

I need to know if possible to use sapftp of a higher release on SAP 4.6C system and if any other solution or investigation points to check on this issue?

    Hi Jonathan

    From the looks and description of the issue , there should be no problem to use the higher SAPFTP version .

    Will search for any docs relevant to the issue and let you know.

    Thanks

      Just an update for those that may encounter the issue:

      SAP Active Global Support has confirmed that since there is no issue in using SAPFTP from a higher kernel version, then it is okay to use this on 4.6D EXT2 SAP Kernel.

      Cheers.
