Access Violation Error Message in RPCSS with Endpoint Mapper RPC Requests (271794)
The information in this article applies to:
- Microsoft Windows NT Server 4.0
- Microsoft Windows NT Server, Enterprise Edition 4.0
- Microsoft Windows NT Workstation 4.0
This article was previously published under Q271794 SYMPTOMS
If you are running RPC-server programs that communicate with their clients over TCP and/or UDP and you are using dynamic endpoints while under load and experiencing network problems, you may receive an access violation error message in Rpcss.exe. When this occurs, you may need to restart the server to work around this problem.
CAUSE
This problem can occur because when information that is stored for datagram RPC requests is freed, an invalid pointer is freed that causes the access violation error message.
