Hi
I develop web application and use WSA. WSA and Application Server works in state-free mode.
95% of code are Non-persistent procedures, but for some services I have to call Persistent procedure to create Appserver side remote object.
This object exclusive locks some data while user editing information on client side.
If user abnormally closes Internet Browser window I cant call Release Method to release this Remote Object. As a result I have -1 application server thread + lock of data forever.
I have read documentation and found information about staleO4GLObjectTimeout WSA parameter.
As I understand it is Watchdog (garbage collection) parameter. I set it to 300 (5 minutes). If user abnormally closes browser WSA deletes ProcObject, deletes remove Object and then release Appserver thread this session. Everything works ok, but....
If I call any Procedure after WSA did Proc Object Delete (by timeout) Application cant use this Web Service anymore because to every call I will get WSA Error. The only way to solve a problem - disable + enable Web Service (reboot it).
If I set staleO4GLObjectTimeout to 0 application works OK.
So I have a question. Is it a WSA bug or I have to set some other WSA parameters.
