Well, I can take a look at the latest re21...

Doublechecked, only -O optimization on both OpenLDAP and BDB builds. And
the BDB tests appeared to complete successfully, I'm running them again
just to be totally sure.

I can't find anything in the slave logs. Running at loglevel 256 to avoid
catastrophic overlogging and performance issues, since this is a
production server. I've started running the slurpd as a background job
with -d 255, redirected output to a file. Am waiting for a fault....

Hmmmm... wonder why it suddenly got so hard to do... :-/
One things I've been doing that I've stopped, to avoid confusing things...
I had been shutting down the master and the slave nightly (one hour apart)
with SIGTERM before slapcat'ting the database for backup. I don't know
why that might cause problems, but...
I've upgraded the system to Sun's latest recommended patchset also, it was
slightly out of date, and rebooted. So far, I've run 24 hours without a
failure, I'll keep watching.
