I see Lc0 crashed one time.
May be it was in this game.

If Lc0 crashes three times, is it out?

Don't worry, the problem isn't in Lc0:

Code: Select all

From Twitch chat:
Moderator kkeronen62: I checked the log and Leela disconnect was network issue: 199193786 <LCZero v19.1-RC2-11248(90): FATAL ERROR: Network error: Software caused connection abort Terminating process of engine LCZero v19.1-RC2-11248(90) 199194816 >Xiphos 0.4.14(91): quit Finished game 46 (LCZero v19.1-RC2-11248 vs Xiphos 0.4.14): 0-1 {White disconnects}

It was a connection issue between both computers (the gpu engines one and the cpu engines one). I have NEVER seen Leela crash in all the gauntlets I've made.

Yes, it was manually adjudicated as a win for Leela. It was already a win for white.
