SYMPTOMS
If a low memory condition occurs during a replication, Content Deployment may fail to accept new connections.



CAUSE
Under low-memory situations, the _beginthread call can fail as the thread pool is expanded. The internal counter tracking the number of threads in the thread pool is increased even though the call fails. When the thread pool is later decreased to 1 (using the internal counter, which no longer reselects the actual number of active threads), there will be no active threads, and all incoming connections will fail.



RESOLUTION
In this condition, the thread pool will never grow. Therefore, the only way to recover is to stop and restart the service.

To resolve this problem, apply the next Site Server 3.0 service pack when it becomes available.



STATUS
Microsoft has confirmed this to be a problem in Site Server version 3.0. This problem was corrected in the latest Microsoft Site Server version 3.0 U.S. Service Pack. For information on obtaining the service pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
