Hi all,

We are facing a weird issue where a similar configuration is yielding
unexpected results for consecutive requests on Tomcat 7.0.54.

We have enabled the request dumper filter on Tomcat 7 and it shows that
consecutive requests are missing the parameters.

Due to this our application is throwing a backend error and giving a bad
user experience of not letting the user complete a transaction.

Did anyone face a similar issue on Tomcat 7 ?I can share more configuration
files as required to help give more details on the issue.

Helpful pointers are greatly appreciated.

LOG link:

http://www.filedropper.com/requestdumper

TCP dump -8009
http://www.filedropper.com/tcpdump

Additional Info:

We are not aware of any specific pattern.The transaction is going through
Browser [HTTP | Port 80] >> Web Server [HTTP | Port 80] >> Mod JK [AJP 13 |
Port 8009] >> Tomcat [AJP 13 | Port 8009].The parameters are submitted
through a form POST.We roughly see this issue once in 5 times.The log which
we shared is from the tomcat's request dumper filter which is supposedly
the first filter before any of the application level filters are invoked
which means that our application is not even receiving them.Hope this gives
you a better idea.


Added the tcp dump for port 8009 which is the last layer before the request
dumper log and the parameters are found in both the cases.(please ignore
the file name in the logs)
