TLC fingerprint value already on disk

[Dominik Hansen <do.han...@xxxxxxxxxxxxxx>]

Hi,

TLC reports the following error message when I run it on my model with a large state space:

Progress(45) at 2015-05-20 13:52:02: 16033373 states generated (2.015.370 s/min), 11993254 distinct states found (1.995.379 ds/min), 1277839 states left on queue.

Error: TLC threw an unexpected exception.

This was probably caused by an error in the spec or model.

See the User Output or TLC Console for clues to what happened.

The exception was a java.lang.RuntimeException: DiskFPSet.mergeNewEntries: 9223335424116589377 is already on disk.

Does it mean there is a (detected) hash collision?

Is there a workaround to avoid this error?

Thanks

Dominik
