Hi james2vegas, sorry for the delay in reply.

Well, I thought I had surmounted this problem, but no, it is back with a vengeance. Here is what is going on in a single web action -- 

    SELECT col1 FROM table WHERE condition;
    if (col1 exists) {
        UPDATE table SET col2 = <new value>
    }

Well, I get the "db is locked" error at the UPDATE statement. Now, in my httpd.conf I started using 

    PerlModule Apache::DBI

[download]

and I thought my troubles were over. Except, this lock problem has started rearing up again. I have tried a few other things, such as starting every db action with $dbh->begin_work and ending with $dbh->commit, but I am already using AutoCommit => 1 so I am not sure if that even has any effect. I have even tried sqlite_use_immediate_transaction => 1, but that doesn't help either.

My application is being loaded in Apache conf file with 

    <Location />
        SetHandler perl-script
        PerlHandler Plack::Handler::Apache2
        PerlSetVar psgi_app /path/to/application.pl
    </Location>

[download]

So, I want all the perl modules to be loaded when Apache2 starts, and then a $dbh created for each user when the user comes to the web site, but not recreated for the same user on every reload. I am assuming that would be the correct way to work speedily.
