Frequent Issues

Running out of Memory

If AptaSuite fails due to insufficient memory with error messages alike

java.lang.OutOfMemoryError: Java heap space

or similar, try to run AptaSuite with a larger heap space. By default, Java tends to allocate only a small portion of the available system memory. This behavior can be adjusted with the -Xmx option. For example, to allocate 20GB for AptaSUITE, the following option can be added to the command line (notice there is no space between the Xmx and 20G):

java -Xmx20G -jar aptasuite.jar OPTIONS

Please note that the upper bound depends on the memory availability of your system.
