Missing SRTM file --> java.lang.NullPointerException

[obarrilero]

Have you tried to modify the snappy.ini file to increase the java memory?

Calculating and setting VM parameters in Unix comandline

You can modify the snappy.ini file by script. Change the line # java_max_mem: 4G to e.g. java_max_mem: 6G The value could be computed by the (Python) script based on the memory available. There is also the snap-conf-optimiser. Which can be used to find a suitable configuration. But this is not really applicable in your case, because it doesn’t change the configuration of snappy/jpy.
