On Ubuntu 10.04 64-bit linux on an intel i5,
myriadcoin-qt
Myriad Core version v0.9.2.16
got to about 1yr 30 weeks to go and then crashed.
restarting got the same crash and various unhelpful "corrupt database" excuses.
deleted /.myriadcoin/ and tried again
my third attempt has so far got to 44 weeks to go so it has got past where it crashed the first time.
I'll post again if asked to or if it needs more doing to it other than delete the -datadir reboot and restart
how much "free" memory do you have on your system? as in send me the output of running 'free -m' from a console window.
