CREATE SAX-READER or CREATE SAX-WRITER hangs -- 11.7.5 on AI

AIX 

We are in the process of upgrading from 10.2b to 11.7.5 and have run into one issue so far.

This error was reported from Proxygen generate JAR.

Open4GLException occured com.progress.open4gl.dynamicapi.SessionPool$NoAvailableSessionsException: SessionPool : NoAvailableSessions[Request failure: Server refused connection (7251)]

We're confident it's not a problem with the JAR per se.

A review shows that all the AppServer agents are hung and not responding.  Stack traces from each of the hung agents shows that they are all stuck at either a CREATE SAX-READER or CREATE SAX-WRITER statement.  Further testing in a simple procedure editor window confirmed that an 11.7 session will hang whenever attempting to execute either of those statements.

A couple of our thoughts:

- 11.7.5 installed along side 10.2b

- DLC directory is a symbolic link

It appears this is NOT limited to AppServer calls. A stand alone pro session with no connections to anything, also hangs when attempting to create a SAX object.

Has anyone else run into this or have an knowledge of a resolution? We will also be raising this with Tech Support.

TIA
