<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><span lang="EN-US">The scenario:<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">First we create a new DWG-file and establish a new FDO-connection to the PostGIS. Everthing works fine.
</span>All data will be queried and shown in AutoCAD.<o:p></o:p></p>
<p class="MsoNormal"><span lang="EN-US">Next, the file will be closed, the local „MapCache“ delete and the DWG reopened. It’s the same as opening the file on a second workstation.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">During the startup/opening the FDO-connection will be automatic recreated. At this point AutoCAD Map freeze/crash.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">If we don’t save the password for the FDO-connection, the DWG opens fine because the FDO-connection keeps closed. Only when the connection to the Postgis will be recreated AutoCAD freezes again.<o:p></o:p></span></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><span lang="EN-US">Sometimes the connection can be reconnect without errors. But later if we refresh the PostGIS layer in Autocad Map it crashes again.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">The error can be reproduced on different Systems:<o:p></o:p></span></p>
