[SHARE] GAB - Gekko Automated Backtests

[simpsus]

I have the same situation with multiple strategies:

backtesting in gekko works fine.
parameter iteration with gab immediately gives me curl status 500 with

Error: non-error thrown: Child process has died.
at Object.onerror (/var/www/html/gekko/node_modules/koa/lib/context.js:105:40)
at process._tickCallback (internal/process/next_tick.js:109:7)

in the gekko console.
As this is the case with different strategies and single runs with gekko work fine: Do you have an idea what is happening or what I could to to investigate? Thanks!
