Crash: out of memory, and instance slow when restarted
My instance crashed:

```
asyncfutures.nim(372)    read
asyncfutures.nim(372)    read
asyncfutures.nim(372)    read
asyncfutures.nim(372)    read

```

Since I restarted it it super slow, and sometimes 504.

After a while it crashed again:

```
