SYMPTOMS
The Linkage Directory Exchange Agent for Lotus Notes version 3.2 may access violate when encountering a Lotus Notes document Fullname attribute that is greater than 252 characters. The resulting crash will include LSDXANTS!LNDXAProcessOutbound in the stack frame.

The Linkage event log will look similar to the following when this occurs:

The process DX Agent for Lotus Notes (DXANOTES) will be set to "Generating Updates" in the current activity column in the Linkage Administrator Process Manager window.



CAUSE
The Directory Agent for Lotus Notes allocates a maximum buffer of 252 character for the Fullname field. It provides no error handling when a Fullname string greater than this is encountered. This causes the process to overflow the buffer, corrupt the stack, and eventually access violate.



STATUS
