        I am encountering the following:

                daemon: select failed (22): Invalid argument

        This only seemed to crop up when I was attempting a syncrepl.
However, after seeing where its occurring, it's not clear to me that it
might not be able to occur at other times. 

Config:
        Sparc Solaris 9
        openldap 2.2.23
        db 4.3.27

        Below is some output demonstrating the problem. Note, I did add
some debug print statements to ../servers/slapd/daemon.c . I have
annotated them below. It appears that a large negative seconds is passed
in the time structure to select. That is what is causing the invalid
argument. 

        I managed to "fix" this for now, by changing an equals
comparison to a less than or equals. I didn't explore the logic real
close, so I am not sure if this is the best thing to do or not.

        I have also included a diff, showing my debug print statements,
along with the comparison change I made to get around my immediate
problem.

BTW -- 

         I have also encountered a number of what seem to be already
reported bugs about the syncrepl provider server terminating after an
improper termination of the client machine.

        Maybe, it is documented somewhere and I missed it. It made all
the difference in the world to index entryUUID. If this isn't
documented, it really should be. 
         
        I think this syncrepl stuff is pretty cool and I really hope
those working on it can get the bugs worked out. I really appreciate
their efforts ! :)


                                                        Thanks,

                                                        Robert
