I'm wondering the following things:

1) Is it possible that one of the ITS's for syncrepl that will be
included in 2.3.42 would address this crash?  Any suggestions on tracking
down why it crashed?

You may have hit the accesslog callbacks bug (ITS#5490).

Looks likely. Then, I need to research why I didn't get a core file (likely a ulimit problem)

2) Does it appear that I have a configuration problem (the delta-syncrepl
taking about five times as long to get the changes out to the replicas as
it took to apply them on the master)?  Where would you suggest I look if
it is likely?

Have you set up a DB_CONFIG file for your accesslog DB that's reasonable?

I think it's reasonable ;-) I have two DB's and 4GB of memory on this system. The DB_CONFIG for the accesslog DB is as follows:

set_cachesize 0 524288000 2
set_lg_bsize 2097152
set_lg_regionmax 262144

Have I missed something that would be more reasonable?

The DB_CONFIG for the other DB has the following:
set_cachesize 0 524288000 2
set_lg_bsize 2097152
set_lg_regionmax 262144
set_lk_max_locks 4000
set_lk_max_objects 2000

(The lock/objects were increased from the defaults in response to lock/object issues with 2.2 a couple of years ago).
