ResourceExhausted error while running the Node Audit

[remnantdev]

We run into a ResourceExhausted error while running the NodeAudit report.

Error received from peer ipv4:10.9.82.14:8465","file":"/var/local/git/grpc/src/core/lib/surface/call.cc","file_line":1075,"grpc_message":"grpc: received message larger than max (214449486 vs. 209715200)","grpc_status":8}

• The error does not seem to be dependant on the requested time range.
• We run the report with DisableFiat:true and UnknownGranularity.
• This error occurs on only one of our nodes presumably the one with the most onchain transactions.
  • We do use our LND node to send and receive onchain transactions
  • Looking through the report code, it seems that all transactions are requested from the LND Server in a single RPC call which could be over the maxMsgRecvSize of 200MB and would explain it occurs no matter what the requested time range.

Expected behavior

Node Audit should produce the report.

Actual behavior

Node Audit should produce the report

To reproduce

This error now occurs systematically on one node when we run Node Audit

System information

• Connecting through gRPC
• Version: Faraday v0.2.11-alpha

Hey, thanks for the report. You are correct, the receive size is too small. We should really start paginating calls to ListTransactions, but in the meantime, can you please try with #178?

[remnantdev]

We have deployed a patched version and the report ran successfully!

On the first run we received a deadline exceeded error. We might also want to increase the default deadline.

I pushed a new commit that adds the --lnd.requesttimeout config options that takes a duration. So you can bump it to --lnd.requesttimeout=2m or whatever you feel is appropriate (note the time unit suffix, without a unit I believe this is in nano-seconds).
