I have checked there is no issue on switch on which these interfaces are connected.
No crc errors.
These interfaces are full duplex and 1000Mbps autoneg on on both machine and switch
I don't know why such errors pop up everyday

Man Page for in.mpathd (All Section 1m) - The UNIX and Linux Forums

Cannot meet requested failure detection time of time ms on (inet[6]
interface_name) new failure detection time for group group_name is time
ms
Description:

The round trip time for ICMP probes is higher than necessary to
maintain the current failure detection time. The network is proba-
bly congested or the probe targets are loaded. in.mpathd automati-
cally increases the failure detection time to whatever it can
achieve under these conditions.

Improved failure detection time time ms on (inet[6] interface_name) for
group group_name
Description:

The round trip time for ICMP probes has now decreased and in.mpathd
has lowered the failure detection time correspondingly.

Congestion and too aggressive failover configuration? If an ethernet fails over, the old will be in Windows arp cache 5 minutes as I recall, soooooooo . . . .

Network /firewall problem
I have faced the same sometime back.
If no hardware problem on your side its better check with network admins to see if theres any firewall or network/traffic problem..

This is fairly normal for ipmp ..note:
Improved failure detection time 245*** .. the detection time is getting shorter..

There should not be anything wrong there ..
