You have been subscribed to a public bug: Running octavia-api in a container (kolla-ansible), where a health monitoring process creates OVN provider loadbalancers with listeners, pools, members, health-mons and tests them and cleans them up again. Upon creation of resources, the octavia-api process creates `[eventpoll]` file descriptors (with `epoll_create1()` system call which it never closes. Once it hits 1024, it errors out with ``` 2024-04-09 03:00:12.130 732 ERROR ovn_octavia_provider.ovsdb.impl_idl_ovn [None req-eefd1e9d-8bfe-473d-9ff1-5a8b0d4ab5d2 - 2767ef0256804b92ae0e51e3a99f809a - - 93db18cb391748009639058c52577527 93db18cb391748009639058c52577527] OVS database connection to OVN_Northbound failed with error: 'filedescriptor out of range in select()'.
