PQ98256 resolves the following problem:

PROBLEM SUMMARY:

USERS AFFECTED:
All WebSphere Application Server users.

PROBLEM DESCRIPTION:
Heavy inter-server transactional work can cause a server to hang

RECOMMENDATION:
When running a heavy distributed workload across two servers using interop mode, one of the servers appeared to hang. That is, no new work was being started, and transactions were not completing successfully.

The problem was caused by the subordinate server holding a lock when registering back to the superior upon receipt of a transaction.

PROBLEM CONCLUSION:
The CoordinatorImpl class will be updated so that when a transaction is imported from another server, the registration back to the superior server will be done while not holding a lock.

This fix is available via interim fix PQ98256.
