FOUND THE WORKAROUND:
---------------------

http://dev.mysql.com/doc/maxdb/changes/changes_7.5.00.11.html

Fixed Problem: (PTS Message 1127638, fixed in 7.5.00.11)
appearance:
A LogBackup is started and the kernel crashes with the errormessage
"Assertion of state Log_SaveIterator::CheckPageBuffer pagebuffer
contains no endOfLogDevice failed!" in the file knldiag

Preconditions and circumstances:
A logRecovery lead to a restart by the command
recover_ignore, also this command should have been
rejected by the kernel.

Workaround:
Try to determine, which changes had been lost by the
recover_ignore (have a look at the timestamps of the not
recovered logbackups). If nothing had been lost, clear the
logvolume and do a complete backup. Otherwise the
recovery has to be reeated including the previously not
recovered logbackups.

Solution:
Code-correction: A recover_ignore is only allowed,
when the logvolume is cleared.


THE QUESTION:
-------------
- What exactly does this Workaround mean for us?
- Which timestamps of which files?
- How do I clear the logvolume?
- Is the Logvolume the file: /var/opt/sapdb/ONLINE/DISKL001 ?
- Are the Logbackups the files: /var/opt/sapdb/ONLINE/autosave.001 .002 ....?
- Why shall I do a complete backup afterwards?


Thank you very much in Advance,
Greetings, Andre'
