CORE: NCP Engine cores in

Novell eDirectory 8.8.2 for Linux
Novell eDirectory 8.8.3 for Linux
Novell eDirectory 8.8.4 for Linux
Novell eDirectory 8.8.5 for Linux


NDSD process will core in the NCP Engine randomly. 


In order to have this problem resolved, we need to have a newer version of novell-ncpenc: 
  • OES2SP2 ships with novell-ncpenc-5.1.4-0.6
  • eDirectory 8.8.5 FTF2 on Linux (non OES) ships with novell-ncpenc-1.2-9
Once we are running with newer versions than the ones mentioned above, the fix for this issue should be checked in.
These updates should be available through the OES2 Channel (in case of OES2 servers).

Additional Information

During the process of debugging this problem, we noticed the following:
  • In this case, all the servers affected were running OES2SP2. Due the fact this issue is related to NCP/file operations, we most most likely will not see this affecting eDirectory on Linux servers (non OES).
  • The core happens when we have files with special characters in their names (ie: ó, é, á, ê, í, ç, ã).
  • This core might affect both 32 and 64 bit versions.
