oook i hope i understood, the problem here is because ncurses is not threadsafe

once calls to ncurses doesnt crash we may be able to see the error message that the gateway is trying to print (but failed cos ncurses was doing something else)

:koala: do you have more than 1 cpu?
(ima try to synchronize ncurses calls meanwhile)

The VPS has 2 cpu cores but I am running multiple instances of K

no problem about the multiple instances, but a single K instance may be calling a single loaded instance of ncurses from the main thread and from an async function at the same time while using both cores

Happened again - if it helps it only happens when there is a successful trade.
