Stack Overflow error while saving a vsm / testcase

[VenkateshSatturi]

Hi,

 

I have a requirement like  Create a new XML request using some of the XML elements of incoming virtual service XML request and send this request to multiple downstream systems.

I have used 25 xml xpath filters to save these elements and constructed a new request message using parse text as response step.

 

Incoming VS XML request:  > 2500 lines of XML

constructed XML - 170 lines of XML - (Many of the elements are parameterized using xpath filters - dynamic values)

constructed XML after the filter property values are substituted : 3000 lines of XML

 

I'm unable to save this file , the workstation is getting hanged when try to save. I have checked the workstation.log and observed stackover flow error.

I have also tried to increase the stack memory to 4MB but still facing the issue.

 

Below are the contents of my workstation.vmoptions

 

# Enter one VM parameter per line
# For example, to adjust the maximum memory usage to 512 MB, uncomment the following line:
-Xms2048M
-Xmx4096m
-Xss4m
# To include another file, uncomment the following line:
# -include-options [path to other .vmoption file]

 

Thanks,

Venkatesh

Hi Venkatesh

             Could you please share the file : <lisatmp_10.4.0>\enterprisedashboard.log

Hi Sankar,

 

In our project we were provided access only to portal and workstation. All the other Devtest components are maintained by separate Tools Team. I can request them but this would take some time. May i know why we need Enterprise dashboard log for this ?

 

We are using Devtest Workstation 10.0, where as the other components are 10.3 to my knowledge.

 

Thanks,

Venkatesh

You cannot use a DevTest 10.0.0 Workstation connecting to a Registry that is 10.3.0.  

 

Registry, Portal, Broker, Coordinator, Simulator and VSE must all be at the same version.

 

Please use a DevTest 10.3.0 Workstation and let us know if you still get the error.

 

Regards,

Marcy

My bad, please share workstation.log file. Btw, what Marcy says make absolute sense. Please read more on mixing component versions: https://docops.ca.com/devtest-solutions/10-4/en/installing/preparing-your-devtest-upgrade/additional-upgrade-details#AdditionalUpgradeDetails-MixingComponentVersions

You can comment out -Xss setting, restart workstation and retry.

Thats a good catch. Is this -xss a valid JVM arg ? I couldn't find this entry in ORacle Java doc: https://docs.oracle.com/cd/E22289_01/html/821-1274/configuring-the-default-jvm-and-java-arguments.html

Hi All,

 

I have used -Xss to increase the thread stack size.

 

The issue is resolved now, Issue is because of having one property name substituted as {{{{test_filter}}}} instead of {{test_filter}} in parse text as response step by mistake.

 

It might be going to infinite loop in validate this xml and getting stack overflow error.

 

Thanks,

Venkatesh
