Too many open files & failed to lookup address information: nodename nor servname provided, or not known

[witter-deland]

I tried the following:

1. deploy the canister
2. call update method of canister

I expected to see this happen: call method success

Instead, this happened:

Is this dfx output or replica (dfx start) output? Also, how can I reproduce this?
