Axis2 client stub fails randomly under load with a Parser error
---------------------------------------------------------------
Key: AXIS2-3068
URL: https://issues.apache.org/jira/browse/AXIS2-3068
Project: Axis 2.0 (Axis2)
Issue Type: Bug
Affects Versions: 1.1.1
Environment: IBM AIX 5.2
IBM JDK 1.4.2
2 WAY SSL
Reporter: Shameen Pillai
We are using axis2 (1.1.1) generated webservices client stub with xmlbeans.
This client stub is used to connect to a web service over 2 way
(bi-directional) ssl.
The problem is that under load (~ 7 transactions per second), the stub throws
the below exception. The approximate failure rate is 0.005%. Even though it is
a very small percentage, it is preventing us from using axis2 generated stubs
for what we are trying to achieve.
Please help.
Thanks,
Shameen Pillai
