INTRODUCTION
List of issues fixed
This hotfix fixes the following issue that was not previously documented in a Microsoft Knowledge Base article:
- Live Communications Server 2005 may randomly stop responding (hang). When this problem occurs, end-users can no longer send or receive instant messages.
This problem occurs because of a time-out timer processing problem in Live Communications Server 2005. This problem occurs because the ObjectManager component in Live Communications Server 2005 may take locks in an incorrect order. Therefore, a deadlock condition may occur in the ObjectManager component.
