Technote Number: 1181999
Problem:
This issue was reported to Quality Engineering and has been addressed in Domino
6.0.5 and 6.5.4. The problem is known to occur only with S.U.S.E. Linux
running on zSeries.
Excerpt from the Lotus Notes and Domino Release 6.0.5 / 6.5.4 MR fix list
(available at http://www.ibm.com/developerworks/lotus):
SPR# GCHN646PDR - On Linux, when a fault signal was delivered, a context block
that will supply the PSW, registers, etc, of interrupted process was expected.
We have seen cases where its address is 0 on input, and the code did not handle
it, causing a second fault. This fixes the case of the missing context block;
we will not double-fault.
What happens in certain cases is that a second fault occurs during fault
recovery because of a missing context block for the initial fault. This
missing context block triggers a second fault, causing a core dump to be
written during fault recovery. This behavior can be confusing because the
second core dump is for the fault during fault recovery, not the original panic.
This problem does not affect the usability of the core files. IBM Support can
continue to use the resulting core files to diagnose the situation. However,
the Domino NOTES.INI setting DEBUG_ENABLE_CORE is required to generate a core
dump. For additional information on this setting, refer to "Directing Core
Dumps to Another Directory for Domino on zSeries" (#1180947) More >
