SYMPTOMS
========

If you open a large pool of logical units (LUs) in SNA Server Manager, one of
the following traps may result:

  function: CTN3270AddressItem::`RTTI Complete Object Locator'
  FAULT ->677048b0 0000             add     [eax],al                     ds:677026e4=ac

At other times, SNA Manager may not cause a Dr. Watson error, but may appear to
stop responding (hang), or the SNA services may appear to go offline and then
recover (in the SNA Manager view--the services do not actually shut down).
