Hi @falcucci @scarmuega is this a known issue with Pallas?
@jpraynaud no, it isn't.
For what I read in the issue, if the error was reproducable through the cardano-cli, this is likely to be an issue with the node instance.

Thanks for your answer @scarmuega!
I guess the problem is occurring in one of the routes of the REST API of the aggregator instead.
Closed with #1804
Why
The aggregator of the
release-mainnet
network stopped producing certificates and missed in particular the production of the Cardano db snapshot for immutable file number5917
. After investigation, it appears that the aggregator stopped operating properly as it was unable to retrieve critical information (Tip of the chain) with the local state query mini-protocol: a problem occurred during the connection to the mini-protocol with the error messageResource temporarily unavailable (os error 11)
. We were able to reproduce the problem with the Cardano cli and received the same error:<socket: 11>: resource exhausted (Resource temporarily unavailable)
A restart of the Cardano node was sufficient to reactive the local socket and the aggregator resumed its operations swiftly after the restart.
The Cardano node (
8.9.0
) was up and running for3
months, and we have never noticed that problem earlier.What
Investigate possible cause for the resource exhaustion on the socket.
