APPLIES TO
- Microsoft COM+ 1.0, when used with:
- Microsoft Windows 2000 Standard Edition
- Microsoft Windows 2000 Datacenter Server
SYMPTOMS
On a computer that is running Microsoft Windows 2000 Advanced Server, when you try to load Microsoft COM+ components that are deployed in Microsoft Application Center 2000 Component Load Balancing (CLB), the load may not be balanced as expected.
CAUSE
This issue occurs if two COM+ components try to load at the same time. Both COM+ components have an equal chance of becoming the load balancing activator. The threads of the components experience a race condition when they try to create the load balancing activator object at the same time.
When thread A initializes the object, thread B uses the load balancing activator object that is being initialized by thread A. This condition prevents thread B from obtaining the correct load balancing activator.
Because thread B is accessing the load balancing activator object while thread A is initializing it, the returned object is not a load balancing activator object. Therefore, the object that is returned to thread B does not activate against the remote server. Instead, the object that is returned to thread B activates on the local computer (DLLHost).
