Environment

Novell eDirectory 8.7.3.8 for Linux

Situation

When ndsd memory consumption is close to the maximum available memory, ndsd may core

Resolution

Apply eDirectory 8.7.3.9 (or greater)

If an upgrade is not possible, reduce the amount of memory allocated to eDirectory.
  1. Configure eDirectory cache to be static and preallocated.
  2. Reduce the modules loaded into the ndsd address space.
