<br>
There are various problems with large (> 2GB) MDR files.<br>
I don't know if this is a special problem with the index or with one of the routines that copies the data.<br>
<br>
I see e.g. a *_mdr.img file > 2G that looks not bad but the corresponding gmapi folder shows a file with 0 bytes.<br>
<br>
Just starting to understand that part of the program ...<br>

okay - I will remove the patch again. Yes I was still using it. Still I will need to wait for tomorrow to start analysing it again.<br>

Hi Felix,<br>
<br>
I think a lot of things can go wrong when sizes reach the 2G barrier. Don't use the overflow2.patch, it might be part of this problem.<br>

Ah okay, it's about gmapsupp.img - right now my server is busy, but I will see if I can find an offending tile or if there are some size limits. And yeah the data again is pretty big. But RAM should not matter if there is no Index I thought.<br>
<br>
I will check it tomorrow - at least i know a bit what to look for.<br>

Hi Felix,<br>
<br>
I try to reproduce the problem with the block calculation by adding nonsense strings to Mdr 15.<br>
Maybe this helps to find out what's wrong in a reasonable time without crashing my own disk ;)<br>
<br>
I probably cannot reproduce real size problems because I have only 8G real memory in my PC.<br>

Hi Felix,<br>
<br>
looks like another problem with the calculation of blocksizes, this time a value of 0 is returned instead of a negative one.<br>
The error occurs while the gmapsupp.img is written, the routine that fails is called for each sub file.<br>
Is it possible to share the input data and style?<br>
If not I can try to add logging statements.<br>
<br>

Any idea what is going wrong here?<br>
I think the result is actually okay...<br>
