cardano-node always using 100% CPU in Daedalus

Open weebl2000 opened this issue 3 years ago • 3 comments

I'm not sure if this is the right place. But I've noticed that when running cardano-node from Daedalus - it always uses 100% CPU.

cardano-node has ghc-options set to disable idle GC. But I suspect that since cardano-node is launched through cardano-launcher it inherits the GHC options set (just RTS -N). Is there anyone that knows more about GHC and RTS inheritance to confirm and perhaps fix this?

@ksaric Sorry for tagging, but you seem to have been the top contributor to this project. Do you know if cardano-launcher could be the cause?

@weebl2000 I'm no longer with IOHK, but having said that, I really doubt this is the case. You should provide more data and information for the folks at IOHK to be able to provide you with an answer.

I can confirm this for 4.9.0 on Linux. Minimum one core, but most of the time all cores are under full load of the cardano-node.
