Hi,

I have had umbrel running for a few months now. All the sudden I have noticed the electrs process is using a lot of CPU. I understand this is the indexing of electrum, but the node has been running for weeks and the blockchain has been fully syncronized

this is what I see on the log files

LOL 170%?!  
That would be the amazing invention of the century, how to use 170% power from what you have.  
Just restart your node, wait to sync and catch up and all will be just fine.  
Sometimes when LND is taking a lot of memory and resources, electrs is getting struggled to catch up.  
A restart of the entire machine (and better a shut down, wait 10 seconds to clear up and then a start) will fix a lot of issues with resources, in special if you have a weak machine like a RPi.

LOL  
sorry what I meant was 170% CPU as reported from the top command. I believe the top command reports CPU usage in relation to the power of 1 core.

Restarted and seems to be fine.  
Thanks
