Hey there, If you're using an OpenStack-Ansible as a deployment tool, you can make an override like that in your user_varaibles.yml and run openstack-ansible os-nova-install.yml --limit nova_compute afterwards: nova_compute_init_overrides: Service: LimitNOFILE: 4096 вт, 28 мар. 2023 г. в 21:59, Michael Knox <michael@knox.net.nz>:

Hi,

This will be the OS you have rabbit running on. You will need to increase the ulimit. "ulimit -n" will provide the current limit for the installed OS and configuration. So you will need more than what's there. There could also be other configuration issues, a normal default of 1024 isn't low for most uses, but you will need to consider that as part of the increase.

Cheers

Hi Team

I see these error in my syslog related to my nova compute service getting hung while communicating to rabbit-mq service

"A recoverable connection/channel error occurred, trying to reconnect: [Errno 24] Too many open files"

Is this a OS related error, or some thing i can change to get rid of this error
