Situation
Since applying the September 2010 Scheduled Maintenance update on Novell Open Enterprise Server 2 Support Pack 2 (x86_64), a newer novell-ncpenc (novell-ncpenc-5.1.4-0.11.9) version was installed.
When Dynamic Storage Technology (a.k.a. : Shadow Volumes) were configured on such servers, customers reported to encounter segfaults in NDSD at times when the DST Copy/Move policy was active.
The segfault occurred while referencing an uninitialized file descriptor in the ShadowMoveFile routine :
Core was generated by `/opt/novell/eDirectory/sbin/ndsd'.
Program terminated with signal 11, Segmentation fault.
#0 0x00002aaaaaafc183 in ShadowMoveFile(int, unsigned int, int, unsigned
char*, int, int) () from
/opt/novell/eDirectory/lib64/nds-modules/libncpengine.so

Resolution
This is resolved in a newer version of novell-ncpenc and confirmed by these customers that initially reported the problem.
