"SNA OLE the number of objects has reached their limit" error message (228924)

SYMPTOMS

When you attempt to insert a resource object within SNA Manager (an LU, user, or IP address, for instance), you get the following error message:

SNA OLE the number of objects has reached their limit.

SNA Server Manager abruptly closes, and a Dr. Watson in Snaexp.exe may occur closing SNA Server Manager.

This article does not apply to the following products:

Microsoft Host Integration Server 2000
Host Integration Server 2000 Service Pack 1 (SP1)
Host Integration Server 2004

CAUSE

The reason for these errors is that SNA Server's Com.cfg file has reached the object limit of 65,535 objects. No more objects can be inserted until the existing number of objects has been decreased. This is an architectural limit that cannot be subverted. The following information is from the SNA Server 4.0 Service Pack 1 Readme:

This release of SNA Server supports a maximum of 65,536 configuration objects in one SNA Server subdomain. Configuration objects represent configurable components of SNA Server, such as link services, connections, or logical units. If you attempt to go over the limit, SNA Server warns you with a beep.

If you need to define more than 65,536 objects, it is recommended that you create an additional SNA Server subdomain or delete any unnecessary configuration information.

RESOLUTION

Another SNA Server in a new subdomain must be created to offload the number of objects. The 65,535 limit is for the subdomain (Com.cfg), and adding one more SNA Server within the existing subdomain will not be possible.
