Strangely, it does not seem to be based on position, but the following sequence causes all of the named engines to fail (I have 6 GB RAM, 64 bit Windows 2008 Server) under Arena 2.01:
1. Set hash to 2 GB
2. Set threads to 4
3. Set time to 1000 seconds
4. Have the engines analyze the original EPD file using "Automatic Analysis" under the "Engines" menu item.

After a couple of hours or so, there will be a failure.

Strangely, it does not seem to be based on position, but the following sequence causes all of the named engines to fail (I have 6 GB RAM, 64 bit Windows 2008 Server) under Arena 2.01:
1. Set hash to 2 GB
2. Set threads to 4
3. Set time to 1000 seconds
4. Have the engines analyze the original EPD file using "Automatic Analysis" under the "Engines" menu item.

After a couple of hours or so, there will be a failure.

Gaviota does not crash in a short test (10 seconds each position) with its own epdtest (solved 20 out 57). Is there any engine that did not crash under your conditions? we should discard that there is a GUI problem.

Could you try Gaviota? or maybe only UCI engines can be set up that way in Arena? I am going to solve that problem in the next release ;-)
