Jsystem test unknown failure using Spirent Test Center - jenkins

Question

I have some weird problem and don't have a clue about how to solve it.
I run automation tests using the Spirent Test Center API on win slave (64 bit 8GB RAM).
As far as I know test center support only 32bit compilation therefore some of my prerequisites is to get 32Bit java from nexus to slave and point my JAVA_HOME to this directory.
when I start my test and get to the init function of TC I don't get any error and Jenkins skip all other stages and finish the job.
when I connect to the slave via RDP and disconnect the test run as it should.
this is the failure:
11:20:07 [system]
11:20:07 [jsystem] 08:20:07: Initializing STC object (Chassis IP: XXXXXXX)
[Pipeline] unit

[Pipeline] // node
[Pipeline] End of Pipeline
ERROR: No test report files were found. Configuration error?
Finished: FAILURE
and after connect and disconnect I get this:
<pre>

11:13:37 [jsystem] STC init pass.

UPDATE:
I manage to find the error:
11:54:58 An unrecoverable stack overflow has occurred.
11:54:58 #

I try to google it and play with the java heap size but it doesn't help.
I don't see any errors in the reports.
Please assist

I think that the problem occurred because I need that user should be login to the agent.
My solution was to set the following registry keys in order to assure this.
https://support.microsoft.com/en-us/help/324737/how-to-turn-on-automatic-logon-in-windows
or by the script:
REG ADD "HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon" /v AutoAdminLogon /t REG_SZ /d 1 /f
REG ADD "HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon" /v DefaultDomainName /t REG_SZ /d domainname /f
REG ADD "HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon" /v DefaultUserName /t REG_SZ /d Administrator /f
REG ADD "HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon" /v DefaultPassword /t REG_SZ /d Pa$$w0rd /f
