SYMPTOMS

  • The information store service becomes unresponsive. Users are unable to log onto mailboxes, and Performance Monitor may show %Processor Utilization for Store.exe at 0 percent.
  • The directory service becomes unresponsive. Various operations, such as resolving a name to a mailbox in the global address list, or checking a name during creation of a mailbox profile stop responding (hang) when users attempt to perform them. In addition, Performance Monitor may show %Processor Utilization for Dsamain.exe at 0 percent.

CAUSE

ESE (Jet) hangs because all threads are waiting to acquire a resource that is owned by another thread. The decision used by threads as to which resources to acquire is based in part on a timestamp, and the timestamp comparison is being performed incorrectly. This incorrect comparison can cause the owning thread not to release the lock on the resource and leave all threads waiting.

The symptoms noted above are usually dependent on system uptime. Although this problem is not reproducible, documented cases encountered this problem on Exchange Server computers running for 30 days or more.
