Oracle Solaris Tunable Parameters Reference Manual

nca:nca_conn_req_max_q0

Description

Defines the maximum number of incomplete (three-way handshake not yet finished) pending TCP connections for NCA to listen on.

Default

1024 connections

Range

0 to 4,294,967,295

Dynamic?

No

When to Change

When NCA refuses to accept any more TCP connections because it already has too many pending TCP connections. If NCA is receiving many TCP connections and can handle a larger load, but is refusing any more connections, increase this parameter. Doing so allows NCA to handle more simultaneous TCP connections.

Commitment Level

Unstable
