If the OOS can be reproduced, but the debug state dumps don't reveal differences, then I would suggest doing two things:

  1. generate a binary state dump in addition to the ASCII debug dump. Because the hashes come directly from the binary state, if there is an OOS, the difference must be there.
  2. decrease time between full state hashes in multiplayer games (default is 20 turns). This way less time passes between the root cause of the OOS and its detection. Just keep in mind it's slow.

These would require changing the code and recompiling, so it's not for everyone. See also the debugging guide.

I haven't been able to reproduce this anymore against other players...though I haven't tested with Oimat.

I played a game with Oimat, and we didn't get an OOS. So I think we can close the OOS tickets.

Reopening, as the cause and fix are now known.

In 15163:

Removes pointless minimap state change during attack notification, it broke synchronized simulation state and caused some OOS errors. Fixes #2525. Refs #1719, #2526.

Note: See TracTickets for help on using tickets.
