Hi,
A user was testing a web application.
Apparently they clicked on a link that opened a report and quickly
clicked the link again.
The web application became unusable and tomcat had to be restarted.
If the issue was a long request time ( perhaps something was going on
with the database at the time this happened resulting in a hang up ).
What can I do to prevent the entire application being unusable for all
users?
Here is the message that was in the logs. This happened on a server
that I don't have access to right now. Here is the message I was given.
I have been unable to reproduce the error myself.
