in.mpathd进程存在问题，可能是配置的问题吧。

man in.mpathd

You will find the answer right there -- close to the end.

有可能是网络的问题。

Oracle的官方诊断描述(http://docs.sun.com/app/docs/doc/816-0211/6m6nc66sm?a=view)：
Cannot meet requested failure detection time of time ms on (inet[6] interface_name) new failure detection is time ms.

The round trip time for ICMP probes is higher than the specified failure detection time. The network is probably congested or the probe targets are loaded. in.mpathd automatically increases the failure detection time to whatever it can achieve under these conditions.

Improved failure detection time time ms on (inet[6] interface_name).
The round trip time for ICMP probes has now decreased and in.mpathd has lowered the failure detection time correspondingly.

故障解释和处理办法：该报错是指，从报文发送到接收返回的时间比指定的检测时间要长。当时的网络很有可能存在堵塞的情况。在这种情况下，进程in.mpathd会自动增加故障检测时间。建议继续观察网络的通信情况，看看是否存在堵塞。

由于系统中设置了IPMP的网卡备用功能，in.mpathd就是这个功能的后台进程。如果的网络负荷比较大，in.mpathd频繁发现他发出的ICMP探测包返回超时，于是系统自动调整了错误探测时间(failure detection time )的数值.但是并没有判定你的网卡坏了，所以没有发生IP切换的动作。如果这些信息在messages中只是偶尔出现你可以不用管他，可能是某个时间网络负荷比较大等原因造成的，如果经常出现就需要分析一下网络状况了，或者修改/etc/default/mpathd中FAILURE_DETECTION_TIME 的数值，改大点。(注意，最小是100ms)
