DS Version: 389-ds-base-1.2.11.15-74.el6.x86_64


How reproducible:

Not sure how easy to reproduce as the import is running for a long time ( 15 hours ) before the crash.

Steps to Reproduce:

Customer was reinitializing a consumer from a supplier using the Console.
After some hours, the consumer crashed.
