Error description
When a user issues clear operation on a map, that already has a pending transaction, it is possible to deadlock the map.
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: All users of WebSphere eXtreme Scale * **************************************************************** * PROBLEM DESCRIPTION: The Objectmap clear operation never * * completes because a deadlock occurs * * when another thread is in the * * middle of a transaction. * **************************************************************** * RECOMMENDATION: * **************************************************************** Deadlock occurred because two threads were in commit phase, each waiting the other thread to complete.
Problem conclusion
The eXtreme Scale runtime was updated to handle the error condition to avoid deadlock condition. This change will be published in future cumulative fixes for the Version 6.1, Version 7.0, and Version 7.1 releases.
