Issue and Steps to Reproduce

I am tail -f ~/.lightning/testnet/lightning.log and seeing:

2023-01-24T04:28:20.331Z DEBUG lightningd: ... feerate estimate for opening hit floor 253 2023-01-24T04:28:20.331Z DEBUG lightningd: ... feerate estimate for mutual_close hit floor 253 2023-01-24T04:28:20.331Z DEBUG lightningd: ... feerate estimate for unilateral_close hit floor 253 2023-01-24T04:28:20.331Z DEBUG lightningd: ... feerate estimate for delayed_to_us hit floor 253 2023-01-24T04:28:20.331Z DEBUG lightningd: ... feerate estimate for htlc_resolution hit floor 253 2023-01-24T04:28:20.331Z DEBUG lightningd: ... feerate estimate for penalty hit floor 253 2023-01-24T04:28:20.331Z DEBUG lightningd: ... polled feerate estimate for min_acceptable (125) smoothed to 196 (alpha=0.44) 2023-01-24T04:28:20.331Z DEBUG lightningd: ... feerate estimate for min_acceptable hit floor 253

When I attempt to run a lightning-cli --testnet lclit withdraw tb1[address] 1000000 urgent 1

The command just sits there and never returns, my lightningd cpu usage jumps to 100%, if I cancel the command, even running lightning-cli --testnet withdraw just sits there and hangs, which woudl normally return a please specify destination

I have to restart my lightningd --testnet daemon, as lclit withdraw just hangs

There is nothing that shows up in the debug log.

getinfo output

Mh that is interesting, what version of cln are you using?

mdance commented 1 year ago

I'm running a compiled version of v22.11.1 on manjaro linux, once it hangs, if I hit cntrl+c, even issuing lightning-cli getinfo hangs, I've got to restart the lightningd daemon before any commands will work

Mh this is a really interesting case, when your command hangs there is any process on your system related to cln that is consuming CPU or RAM?

P.S: do you have any particular plugin that you are running?

Running top I'm seeing lightningd using 100% cpu:

  1 2650791 md        20   0  704.8m 671.7m   3.5m R  99.7   4.3  21.5m   1   0:34.97 /usr/local/bin/lightningd --testnet --pid-file=/home/md/.lightning/testnet/lightning.pid --daemon

I've got the currencyrate, summary, monitor, and c-lightning-rest plugin (for RTL)
