Problem: Connections to an ArcSDE instance on HP_UX hang
Attempts to connect to ArcSDE 8.1 on HP_UX hang. ArcSDE adminstration commands hang when issued with no options.
The HP_UX 11 version being used is older than those tested at ESRI.
Solution or Workaround
Install the latest HP_UX 11 patches.
At minimum install HP-UX B.11.00.52.2 and the patch set from March 2001.
