| i.e., what does truss(1) (assuming FreeBSD (and sometimes Solaris))
output?

This is Linux and I have no truss command. I read your above document,
and I thought I was explaining it well enough. Yes I posted a guess, but
I did not say "Here is my problem, here is my guess as to the cause, how
do I fix this guess?". I said "this is my guess, but I am not positive.
If you have a better idea, I'm all ears".

I looked up truss, and it's equivalant Linux command is strace. Here's
the result of an strace:

And for all those who said to recover the database, that is not working.
I should have mentioned this before, but my standard startup procedure
is to run a recovery on the database then start pksd (incase the server
was shutdown incorrectly for whatever reason, or in case pksd crashed
and did not write the db out correctly before crashing).

I'm nearly 100% convinced it's a database problem because it works
beautifully with an empty database I create.

I am starting the process of exporting the entire database to pgp files
and then recreating the database and re-adding the pgp files, but if
someone has an idea that can fix the problem, I'm all ears!

Thank you,
Dan Egli
