Hi guys I wanted to share with you a GOTCHA I struggled with in the passed few days, maybe it will be helpful for more people
I am using GDAL on a docker cluster, since there are more services running on the host I limit the container to use only 1GB of ram The default behavior of GDAL_CACHMAX is 5% of the available memory, but apparently when running in above setup it sees the System memory, which 16GB and not 1GB. On that container I ran 3 process of GDAL which means it calculated it can use 2.4 GB approximately, but the container limitation was only 1GB The result was that the OOM killer of the operating system killed those processes because they exceeded memory. To solve to issue (to control the memory the process is going to use) I explictly set the GDAL_CACHMAX to an absolute value
