Hi,
I'm afraid I've encountered a memory leak in the hdf driver.
Context: because of massive parallel (cluster) processing, I'm reusing
a python instance for lots of jobs. Some of these jobs use gdal to
read and/or save data. In some cases, I saw the memory use of my
python worker processes grow with each job, until the whole lot got
killed. I've got 8 gig on that server :-). I've been able to track
down the leak to the use of gdal.Open on a hdf (modis) dataset. I
guess this means that either the gdal hdf driver or libhdf4 has the leak.
For the record and possible future googlers: this appeared to be a leak
in libhdf4.2r2; upgrading to 4.2r4 fixed the issue.
Vincent.
