When a read operation fails on a WebSphere managed socket,
WebSphere's internal state flags may become corrupted and
cause future read requests to fail with the following message:

java.io.IOException: ZAIO INTERNAL: only one read operation
permitted at a time on a connection link
Problem conclusion
Support has been modified to reset its internal state flags
correctly following a socket read failure.
