Are you saying the server is crashing when trying to disable
replication?
a'yep In the simplest recreation, I create a new instance and
initialize a suffix in it. Then enable replication as a 'consumer'. Then
try to disable replication. . . . the instance crashes with a segfault
recorded in /var/log/messages. I've done more complicated experiments,
including defining a 'supplier' and populating a 'consumer' with data,
but they all end with a segfault.
