I am running a loop in Jython and have a loop of 100K elements which fills up dictionary slowly and eventually crash the app with error:

java.lang.OutOfMemoryError: GC overhead limit exceeded

I can track how many elements were processed with a print out to terminal of a current index every 10K elements.

How to print current memory when running app in Jython ?

Want to create output similar to this:

10k - 50MB used so far.  
20k - 100MB used so far. 
30k - 150MB used so far. 
...

Thanks.

do you know how much memory each element consumes? – RAZ_Muh_Taz Mar 28 '18 at 23:19
No. But would like to know how much 10k consumes. I also want to know how much memory it is consumed by application (not by me raw counting bytes in e.g. string and multiplying with 100K). – Joe Mar 28 '18 at 23:24
@Scary Wombat - I asked for memory usage via Jython commands - you marked as 'duplicate' question but for Java.. Not sure if you know the difference.. – Joe Mar 29 '18 at 03:16
Sorry Joe - I can't read – Scary Wombat Mar 29 '18 at 03:18
No problem - I added more explanation as well... – Joe Mar 29 '18 at 03:33
