Hi, I hope you can help me analyzing this problem:
I am using Tomcat6 6.0.32-5ubuntu1.1 together with Axis2 1.6.1
I am not sure if it is an Axis2 problem or a Tomcat-problem.
I have an client-application for test-purposes which runs inside the
Eclipse-IDE.
The problem only occurs when running Axis2 inside Tomcat6, when running
in Axis2 as stand-alone server, it runs better.
What I do is posting arrays of strings (about 50 elements, about 5Kb
max) to an webservice-call.
After some validation, the webservice posts the data to a postgresql
database.
I have some console-output to see how long it takes.
storing..... Person:26, ID:27
Creating EHR for:213d7c09-949c-4757-a91d-da5510215472
GUIDs saved to table:213d7c09-949c-4757-a91d-da5510215472,

stored..... Person:26, UID:213d7c09-949c-4757-a91d-da5510215472
PT0.647S
As you can see, it starts with less then a second, sometime 0.3 seconds,
sometimes 1.1 second, depending on the number of elements in the array
to store.
After 1000 persons stored, it takes 4 seconds

stored..... Person:998, UID:49c96d87-38db-491d-a824-78800615e80a
PT4.147S
When running in Axis2 standalone, it stays about 4 seconds until 8000
persons stored (which is the complete group to store)
This is slow, I must investigate the library directly without webservice
if that is a problem of my coding. So we forget that for the moment.
The problem which bothers me is when I am using Tomcat.
The problem start to occur after posting 1200 patients, it takes 8
seconds. When it reaches 1300, it already takes 17 seconds.
When at Person 1330, it is already 29 seconds, and at 1340 it is 39
seconds, and than a few persons more and a time-out exception occurs.
I receive a java.net.SocketTimeoutException: Read timed out from the
client side-code. The default time-out time for Axis2-code is 40 seconds.
The printstacktrace is below, but it is client side stacktrace
I try a lot of things to solve the problem. I put a Thread.sleep(1000);
in my client-code between to postings, I thought, maybe the webservice
needs some rest to do garbage-clean up. Because it looks very much like
a memory blowing up. But it didn't help.
Of course, if you need any information, I will be happy to provide it,
please give some hints how to provide it

Kind regards and much thanks
