StackOverFlow error

[rupenmody]

We have just upgraded from 3.3.1 to 3.4(17082007). When I start ebase designer, it comes up with a dialog asking me to enter user name and password and once these are provided we get a StackOverFlowError.

Please advise

[Sarah]

Try adding the "-Xss512k" parameter to your start_ebase_designer.bat file.

For example:

Code: Select all

%JAVA_HOME%\bin\java -Xmx256m -Xss512k -cp %UFS_CLASSPATH% %JAVA_PROPERTIES% -jar lib/UFS.jar

Can you let us know if this helps?

[rupenmody]

Hi,

It now come up with an error saying
"I/O error contacting server http://172.22.4.74:8080/ufs/designer - check that start designer parmeters are correctly set"

But in the logs there is still the stackoverflow error. if remove -Xss512K parameter then we are back to original problem.

Thanks

Rupen

I have a feeling that I have seen this problem before.

The login box may well be a Windows Username / Password to access a resource on the domain of some description.

Do you have some form of Proxy Server between the client and server, such as Microsoft ISA Server ?

Are you trying to connect to Ebase via IIS ?

[rupenmody]

We are not using it over a proxy, but that would be the ultimate goal. Currently we have a jboss app server running on a machine and from the same machine we are trying to launch the designer.

The stack size limits the number of threads that you can have. If the stack space is too small, eventually you will see an exception java.lang.StackOverflowError

You can fix any stack overflow errors by adding the -Xss parameter to your Java Options for both the Designer and Server startup.
for example:

start_ebase_designer.bat
%JAVA_HOME%/bin/java -Xmx256m -Xss1024k -cp %UFS_CLASSPATH% %JAVA_PROPERTIES% -jar lib/UFS.jar

start_ebase_server.bat
set JAVA_OPTS=-Xmx512m -Xss1024k -Djava.net.preferIPv4Stack=true -Dderby.system.home=%~dsp0/DB
