axis2 1.6.1 concurrency issue?

[Himakar Chennapragada <hi...@us.ibm.com>]

Hello,
We seem to have hit a concurrency issue when using multiple services with 
Axis2 v1.6.1; we also use tomcat 7.0.25.
Under a light stress workload the 2 services seem to get mixed up and we 
receive different operations for different services.  When we try with 
service A with operations 1 and 2 and we have another service B with 
operations 10 and 20, at runtime the server receives service A with 
operation 10 and service B with operation 1.

When we used Axis2 v1.4.1 with Tomcat 6.0.18 there was no concurrency 
issue.  Can you please help if there is a global setting or some global 
receivers preventing service wide execution and working at a global level 
causing race-condition/concurrency.
Best Regards,
