It's crashing trying to read updates from the replication changelog. 

Are you using attribute encryption?
Any chance you have a way to reproduce this?

Since this is happening on only one server then I think recreating the
replication changelog will "fix" the issue.  Just re-initializing that
replica should do it.  Does this server start - so it can be reinited? 
If not, you need to manually remove the changelog and start the
directory server, and reinit it.  Or perform a manual ldif
initialization.  (I can help with either one if needed)
