<DIV dir=ltr align=left><SPAN class=093074804-12022009><FONT face="Trebuchet MS"

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 class=093074804-12022009><FONT face="Trebuchet MS" size=2>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

shows where it occurs and thought someone here might be able to suggest what
could be causing the problem. </FONT></SPAN></DIV>

<DIV><SPAN class=093074804-12022009><FONT face="Trebuchet MS" size=2>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 class=093074804-12022009><FONT face="Trebuchet MS" size=2>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.
