Tuning for Passive Check latency

[Yu Watanabe]

Hello Jim.

Again thank you for your reply.

Following are the stats for the command buffer slots:

Program Running Time:                   3d 15h 5m 58s
Nagios PID:                             17527
Used/High/Total Command Buffers:        4 / 4096 / 4096

it seems that it have already reached the top....

Thank you,
Yu Watanabe
