> 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
> Assignee: Amila Chinthaka Suriarachchi
>
> 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,
