I don't believe there was anything interesting in the JK log file near that
time period.

They are timestamps as you guessed and yes they are a bit strange when
correlating the two sets of log entries. I also forgot to mention that we
have app-side logging and we do know that userB's request to /portal/Login
was received and processed correctly by the application. Knowing that
requests make it through to the application it appears to be an issue on the
response side of the cycle.

We don't have a script to detect these errors and have, to date, relied on
user reports. I may look into figuring out a script to compare the two sets
of logs and see if we can find these that way. I'll also look into adding
the pid and tid info to the logs.
