Javascript heap out of memory

See original GitHub issue

After a while of fairly heavy use (like we use a Parity node in production) Ganache stops working due to an out of memory error. (docker image: trufflesuite/ganache-cli:v6.1.8)

I can also verify that there is definitely a memory leak in ganache. I’ve also observed it while tracking the it with node --inspect in and profiling the memory allocation in chrome devtools (capturing >1 day of data). Memory usage steadily increases including some inexplicable spikes in between. I haven’t yet found the culprit though.

@kevinweaver Both the transaction and the gas estimation work with Ganache v7.0.0-alpha.1. Thank you for the hint about upgrading. 😃
