Zappa Mexico bug on playchess

[Vinvin]

ChessPaparazzi played some days ago on playchess with the Zappa Mexico engine. His level was about 2700 and then suddenly start to play badly and lost 700 points !! (when the operator restarted the engine, everything is ok again)
Is this bug know and/or corrected ?

How do you know it is/was a bug in Zappa?
It can be at least as likely an operator/hardware or
may be even more likely a GUI bug.

Yes, more likely to be a hardware or GUI or even internet connectivity problem

This looks like the problem I had with DS10, and a couple other UCI engines I have.

The engine stops on the last book move, if I remember correctly you need to delete some chessbase parameter files then all will be well.

It's no bug,

ChessPaparazzi uses extremly overclocked machines on Vapochill, he must have been pushing his machine more...This is what happens when you take the risk of overclocking your hardware..

I had 2 problems with Zappamexico on Playchess. I played around 20 games.

That is my account basically what happen i was tired of certain accounts hanging over my games ... I basially load different settings that were not my best. ChessPapaRazzi is not on overclocked hardware. The system of mine that will be over clocked with very extreme cooling will be my EL-SHADDAI account ... Papa runs on an 8 core system and EL will be running on an overclocked QX6850 running at about 4.6 GHz - + 5 GHz. It uses DDr3 with a Vapo system with North and South bridge cooled via peltier's.

Sorry, but I don´t understand English well and sometimes Google translations don´t help.
Are you saying that your accounts hangs many times? I have few
problems playng in Playchess.
By the way, my last game, with Zappa, was against EL-SHADDAI, and
I have a problem, but I think that the game was a win for SHADDAI.
