PRB: "RPC_S_SERVER_TOO_BUSY" When Binding to Server on ncacn_np (176734)
The information in this article applies to:
- Microsoft Platform Software Development Kit (SDK) 1.0
This article was previously published under Q176734 SYMPTOMS
If more than one client connects to an RPC server using the ncacn_np
protseq at nearly the same time, the call may fail with error code 1723:
RPC_S_SERVER_TOO_BUSY
CAUSE
This is due to the way the named pipe transport works. The server side
creates an instance of the pipe for use by clients. The first client to
attempt a connection is associated with that instance. To allow another
client to connect, the server must create another instance of the named
pipe. If another client attempts to connect before the new instance is
created, the server appears (to the second client) not to be accepting
connections.
RESOLUTION
RPC clients should be written to handle a situation where the server is too
busy to accept a connection because it is highly likely that there might be
too many clients attempting to establish a connection at a given time.
Options for handling this situation include automatically retrying,
prompting the user for a course of action, or failing.
STATUS
This behavior is by design.
