Hi,

I am trying to get a layer from wms and at higher zoom levels I am getting this 
error - msDrawMap(): Image handling error. Failed to draw layer named 
'PICT-INHEND19-psQwiZ1L4t'. drawGDAL(): Unable to access file. 
GDALDatasetRasterIO() failed: /tmp/mapfilePassthru-v2-temp-HxmyxI, band 1: 
IReadBlock failed at X offset 1064, Y offset 1551.

So, for this I checked from the imageservice side the mapfile is being created 
correctly and it is also present there and the mapfile contains a gserve 
request for getting the tiles - that is also working fine. So getting this 
error from mapserver only and tried to put debug level 5 and other things also 
in the mapfile but couldn't get any other error, only this is coming. So need 
help in this if anybody knows what exactly is this and i can i debug mapserver 
locally if i want to then i can figure out the exact point where the error is 
coming from.

Thanks,
Raghav Singh
