Trap in Snalink.exe( _bm_rel@04 ) with DCA ISCA X.25 Adapter

• Microsoft SNA Server, version 2.11 SP1

SYMPTOMS

If you run SNA Server version 2.11 Service Pack 1 (SP1) on Windows NT 3.5 (without any Windows NT service packs), you may experience a trap in Snalink.exe (in function _bm_rel@04) when using a DCA ISCA X.25 adapter.

The problem may be encountered if a TP fails to start because it hits a time out condition while waiting for a response from the network. If the administrator then shuts down the computer running SNA Server in an attempt to reinitialize the system, SNA Server may return Event ID 624, indicating that a software component has trapped.

CAUSE

The X25 link service was trapping on termination because the code was attempting to free a buffer twice.

RESOLUTION

Apply the fix referenced below. The updated module is Ibmx25.dll.

STATUS

Microsoft has confirmed this to be a problem in SNA Server version 2.11 Service Pack 1 (SP1). A supported fix is now available, but has not been fully regression-tested and should be applied only to systems experiencing this specific problem. The fix is already included in SNA 3.0. Unless you are severely impacted by this specific problem, Microsoft recommends that you wait for the next Service Pack that contains this fix.
