ERROR Too many open files during node syncing

[PaulZhemanov]

Hi guys! I got this errors in logs during node syncing.

ERROR new{name=node}:initialize_loop{service="ImportTask"}:import:launch_stream{range=2786820..=3985393}:execute_and_commit{height=2786820 id=859cbbb0167f94a266a34bb8b9b41f279bea4246befaa0a2009bfa058bd91aca}: fuel_core_sync::import: 663: Execution of height 2786820 failed: error occurred in the underlying datastore `Other(IO error: While open a file for appending: /home/ubuntu/node/on_chain/233368.sst: Too many open files)`

Hi Paul,

Perhaps this is relevant for you:

Too many open files

What is your server spec ? are you running other nodes / databases/ VMs etc on that same server? Too many open files usually means that a process has exceeded the maximum number of open files you can see the limit ulimit -n then try to temporarily increase it ulimit -n 4096 . and try to spin off the node. You can adjust 4096 to a higher.

Try adjusting the ulimit higher.
