Stephen,<br><br>Do you have information about which function is hanging? Could you provide your test data? I'm not sure about how the SharpMap GDAL connector is currently working but I could probably write an equivalent test case to reproduce it.<br>

<div dir="ltr" align="left"><span><font size="2" face="Trebuchet MS">I'm using GDAL via the SharpMap mapping engine. It makes use of the
csharp wrappers to render imagery (in my case, ECW) to an image control on a web
page. I am currently running it under Windows 2008
Server.</font></span></div>
<div><span><font size="2" face="Trebuchet MS"></font></span> </div>
<div><span><font size="2" face="Trebuchet MS">My problem
is that I am finding that the gdal library is intermittently hanging when being
requested for imagery. I have got a log from ProcessMonitor here (<a title="blocked::http://spreadsheets.google.com/ccc?key=pnbsLIAZM8M_34TfXUVttcA" href="http://spreadsheets.google.com/ccc?key=pnbsLIAZM8M_34TfXUVttcA" target="_blank">http://spreadsheets.google.com/ccc?key=pnbsLIAZM8M_34TfXUVttcA</a>) that
shows where it occurs and thought someone here might be able to suggest what
could be causing the problem. </font></span></div>
<div><span><font size="2" face="Trebuchet MS"></font></span> </div>
<div><span><font size="2" face="Trebuchet MS">Rows 1-40
show a successful map creation operation (including display of ECW image).
Row 41 onwards shows what happens when the image is panned and gdal hangs.
Seems to be associated with 'gdalplugins', but I'm not sure what this is.
Row 64 is the line where it crashed. Row 65 is the start of where I
recycled the web app to get it back from hanging. </font></span></div>
<div><span><font size="2" face="Trebuchet MS"></font></span> </div>
<div><span><font size="2" face="Trebuchet MS">Note that
this runs fine much of the time and has never crashed when I am only displaying
shapefiles. However, when displaying raster images as well, this
occasionally crashes and therefore gdal must be the involved somehow.
</font></span></div>
<div><font size="2" face="Trebuchet MS"></font> </div>
<div><font size="2" face="Trebuchet MS"><span>Any
ideas?</span></font></div>
<div><font size="2" face="Trebuchet MS"><span></span></font> </div>
<div><font size="2" face="Trebuchet MS"><span>Thanks,
