Comment 6 for bug 1780164

I've seen this issue in multiple production Rocky environments.

I found a commit in keystoneauth that properly closes requests sessions (which closes the socket/file handle):

https://opendev.org/openstack/keystoneauth/commit/b2b5ad3cb1ff05e08c22973bb079125214ba7bcf

This commit is included in keystoneauth1==3.18.0. I have tested upgrading to 3.18.0 and initial outlook is good--I'm seeing apache workers open new sockets/file handles and then close them as expected.

Will report back once I have deployed 3.18.0 in more environments and it has been running for a while.
