Well, I was able to repro this:

0. pkill slapd
1. rm [dataDir]/*db*
2. slapd
[...now syncrepl has a lot of work to do...]
3. while sleep 2;slapcat;done &

I can think of no rationale why/how one of the slapcats would have
experienced any sort of abnormal termination.

Does LDAP_DEVEL/-d -1/etc. have sufficient information on lock ids to
track this down? Alternately, I can throw a debugger watchpoint, if you
think that might help.
