It is crashing on two PCs. One instance of Leonardo on each.
On server runs 2 exchanges (Polo/BTCE) with 14 coins total and only about 10 active bots and about 20-30 open orders.

Specs of the server running the above :
Dual XEON X5650's (6-core each, 12core total), 48GB Ram total. Windows 10 Pro 64bit.
This time it's been running for about 3 hours and only using 729MB of ram.
Leonardo crashes randomly after an hour to a few hours. Seems to be that it crashes more as I make changes to orders and bots in quick succession.


The second PC running Leonardo that also crashes is an older Dell server with a Quad-Core Intel Q6600, 4GB Ram Windows 10 Pro also.
It only runs 1 exchange, 8 coins, 5-6 active bots and 16 open orders.

Crashes randomly with the runtime error I'll try to see about getting a screencap of the error next time.

I have not had any dual or multiple orders in a while, but that seemed to go away once Poloniex was back to 'semi-normal' . It is still not as good as BTCE.
Even with these issues, I still use it as it is very effective, but if it would be stable enough to be able to forget for a day or two, it'd be amazing. :-)
