Thank you, Paul.
This is our current setting. Looks like we are at 5 minutes so we should be ok.
net.ipv4.tcp_keepalive_intvl = 75
net.ipv4.tcp_keepalive_probes = 9
net.ipv4.tcp_keepalive_time = 300
There are also a number of IO tuning options for connection life inside LDAP you can tune
to help discard and cycle out stale connections quicker.

If we receive a partial message, how long to wait for the remaining components to be
recieved.

If a client is idle with no messages being received, how long before we disconnect them.

Maximum number of connections. IIRC this might be automatically set from FD's in the
system, but if not you may need to set this to probably 80% of your FD limit frlom the
systemd service tunings you have provided.
Hope that helps,
