I'm going to agree with this being AT LEAST the first place to shift
your focus.
Since the issue you have happens so rarely, you don't really know if
the pragma thing has anything to do within it. All of your tests
seem to be within a margin of error.
How exactly are you logging people in ? How are they identified in
a database? How are they identified to the server after they have
been verified through the db? How are cookies being made / handled /
sent to the server ?
Is it possible that you're experiencing improbable but fully possible
collisions in md5 values?
Also, have you been debugging the actual login logic, and then going
through logs to match up what was happening with an error? there
could be some odd issue where people have similar passwords or
logins, and the verification code sucks.
