There appears to be two separate problems happening in test050.Problem #1) Null cookie is generated, causing catastrophic database loss across the entire MMR cluster (they all lose all their data). This is new with 2.4.48, perhaps related to the revert of part of ITS#8281 when ITS#9015 was fixed (purely speculation on my part at the moment). This appears to be a major/significant regression.
Problem #2) If a MMR node is processing a change during which a slapd shutdown is initiated, it will update the contextCSN of the database but LOSE the related change (at least with a delete op), resulting in a database difference. This is reproducible in 2.4.47 as well (so this is not a regression).
