The high level view is that in 11.x, hastd exits because a "this can never happen" thing happens in primary.c - related to size of data returned by GGATE.  Under 12.0, this gets worse, but can still be worked around.  My main concern is that my "fix" just involves increasing buffer sizes without understanding what causes it to break in the first place, and that performance appears to suffer as a result. Bug 234576 relates to this problem. Paul.
