LibraryService.connect() method hangs

Question

I have a servlet application that uses IFS with Oracle IFS 9.0.1. I have a pool of LibrarySessions that are dynamically created and connected using LibraryService.connect() if a new LibrarySession is needed. Each LibrarySession uses the same login username and password. We have one username and password for the entire web app and the application uses this one user for all calls into IFS.
Here's my problem:
Servlet Thread 1:
Creates a new LibrarySession and begins to stream a file to the client by writing Document.getContent() to the servlet outputstream.
Servlet Thread 2:
While thread 1 is still busy streaming the file from IFS to the servlet output stream, servlet thread 2 attempts to create a new LibrarySession via LibraryService.connect().
Result:
Thread 1 stops streaming the file. Thread 2 hangs and no more LibrarySessions can be created from that point forward.
Questions:
1. Should you be able to perform multiple threads at the same time using different LibrarySessions for the same user name?
2. I'm guessing that thread 1's handles into IFS are somehow blocking thread 2 from connecting and creating a new LibrarySession. Why would this happen? Do LibrarySessions need to be created during a period of inactivity? Is something syncronized in the IFS API that I'm not aware of?

Answers:
1. Yes, you should be able to create multiple threads, each of which use different LibrarySession objects concurrently, even if the LibrarySession objects are authenticated as the same user.
2. a) I'm not sure why this would happen.
2. b) No, LibrarySession objects can be created anytime.
2. c) There are many things in the iFS API implementation that are synchronized behind the scenes, but it shouldn't be causing this problem.
Have you tried iFS 9.0.3?
By the way, the DAV server that is built in to the product works just like your servlet, and supports multiple users connecting and streaming content all at the same time.
Can you connect to the DAV server on your iFS instance and stream content concurrently with other connected users?
