Description: Size of the SYN backlog queue
What is stnPmFirewallTcpSynBacklogQueueSize?
The size of this firewall's SYN backlog queue, i.e. how many half-open TCP connections it will track simultaneously. Admins increase this on busy servers to avoid legitimate new connections being rejected during traffic bursts, while balancing it against memory/state-table limits.
