Hi, the issue seems to be related to paritytech/polkadot#856 and moonbeam-foundation/moonbeam#1410
Please increase net.core.somaxconn
and have try.
Hi, I've increased:
net.core.somaxconn from 4096 to 8192
net.core.netdev_max_backlog from 1000 to 4096
Still seeing "Locating closest peers for replication failed" in logs. It's always happening at xx:39:10 hour:

Hi @wwwAndries Could you check the max open files limit with the help of this link https://unix.stackexchange.com/questions/8945/how-can-i-increase-open-files-limit-for-all-processes
And Did you deploy the node with systemd? Then you should also check this. https://unix.stackexchange.com/a/375841
Also you need to monitor your tcp connections and the number of file_descriptors. That may help to figure the error
@wwwAndries Hi Andries, are you a validator node? what is your validator address?
