Clarification needed : internal error 500

[fboralli]

When running a large code block in a loop it sometimes produces this error:

Code: Select all

Internal Error 500  in "FREEZE(ADF,MODE=OVERWRITE) CENSORED(59).UROOT(ADF,EXOG=CONST,LAGMETHOD=AIC,SAVE=MOUT)".

Censored is a group name.

However, I cannot properly reproduce this error, as it happens once or twice in a run of about 200k tests.
What could I do to verify/reproduce this?

Not a lot, unfortunately. 500 errors are not supposed to be seen, and when they do it means something has gone wrong, but usually in an unpredictable way.
