Dear Orekit team,

I’m performing orbit propagations with the DSST propagator tutorials implemented by Luc Maisonobe on your Orekit DSST Orbit Determination GitLab repository with orekit 10.1. I managed to perform some propagation up to 20 years without problems to test the tool. But, right now I’m struggling with some errors when trying to propagate the same orbit for 100 years.

My initial epoch is 2020-01-01T11:57:20.000 and when I propagate over 100 years a message appears: unable to generate new data after 2070-01-08T23:58:50.816.

I’m running it in Eclipse IDE and I thought it would be a “GC overhead limit exceeded” issue but I changed the heap size on eclipse.ini and the message remains the same.

I saw that it might be a problem related with the ImmutableTimeStampedCache class, but since I am not really familiar neither with Java nor Orekit I hope you can help me with this issue to improve my tests.

Thanks in advance

Kind regards,

Felix
