Hello !

I encountered a similar problem (error Java.lang.OutOfMemoryError ), this issue has been reported on github :

As the answer took to long to arrive, I give up Pilon a month ago, but since someone proposed a way to solve this issue. Maybe you can try his answers :

This essentially means your 90G of allocated memory was insufficient. When Java starts getting towards the limit of the memory specified (-Xmx) it starts to perform more aggressive garbage collection (GC) to free up memory. So as to avoid running GC all the time, instead of running computations, Java will kill the command if the total time spent performing GC exceeds a percentage (I think 98% from memory) of total run time. I reality, I think what this means is that if Pilon is running for 2min before it starts to run GC, then the GC would have to run for 98min before the process is killed. The only general Java solution is to increase the amoutn of memory you make available to Java by increasing -Xmx.

Hope it will help you !

Well, I guess I somehow misunderstand the question ?

No that's a reply typical for this user. Don't take it personal.
