ndo2db: Warning: Retrying message send. This can occur because you have too few messages allowed

问题描述：
[root@nagios log]#tail -f /var/log/messages

ul 16 12:10:47 nagios ndo2db: Warning: Retrying message send. This can occur because you have too few messages allowed or too few total bytes allowed in message queues. You are currently using 64 of 65536000 messages and 65536 of 65536 bytes in the queue. See README for kernel tuning options.

解决办法：

默认 queue 太小

修改系统内核参数，就正常了。

[root@nagios log]#vi /etc/sysctl.conf

#the maximum size of a single message in a message queue
kernel.msgmax = 65536000

#the total number of bytes allow in all messages in any one message queue
kernel.msgmnb = 65536000

#the maximum size of a single message in a message queue
kernel.msgmni = 65536

[root@nagios log]#sysctl -p
