Your technician is sort of right. Koha itself will not work if it can
not connect to the database. Zebra itself never ever connects to the
database.

This is where the confusion is occuring I think we are talking past
each other.

There is a script, that is written in perl, that connects to the Koha
database, exports a bunch of MARC as xml files, then passes those off
to the zebraidx job for it to index them.

None of this requires zebrasrv to be running (the actual zebras server
process). zebrasrv itself never talks to Koha, or to mysql, it only
looks at it's own index files. 

Now, the script to rebuild the indexes will fail if it can not connect
to the database. This looks like what was happening with the error log
you pasted before.

So to be absolutely clear, it is the zebrasrv process that is dying?
And it is not logging anywhere? Not even to syslog?

You are running from the debian packages right? If zebrasrv is dying I
would expect to see things like this 

$ sudo tail /var/log/koha/ashs/zebra-error.log.1

20120314 21:58:00 ashs-koha-zebra: client (pid 2441) exited with 1

$ sudo tail /var/log/koha/ashs/zebra-output.log.1
