[389-users] Database and OS tuning. (open files)


I enabled chaining in our environment to replicate password policy attributes from the consumers and hubs back to the masters and now we are seeing these errors in the logs
We have to reboot for the system to become stable again.

31/Aug/2021:23:31:36.584135966 -0400] - ERR - configure_pr_socket - Unable to move socket file descriptor 42 above 64: OS error 24 (Too many open files)

Is this behavior expected with this change?

Are there any other dirsrv tuning options that you think would be helpful?

Right now, I have made the following changes.

nsslapd-idletimeout: 600

I have bumped nofile for dirsrv from 8192 to 20000. 

dirsrv           -       nofile          200000

We have also set open file limit in the service file for DS

[Service] LimitNOFILE=200000
