Jsystem test unknown failure using Spirent Test Center

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] }
     [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>
 [jsystem] 08:12:58: Initializing STC object (Chassis IP: XXXXX)
 11:13:37    [jsystem] STC init pass.

UPDATE: I manage to find the error:

    11:54:58  An unrecoverable stack overflow has occurred.

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
