loosing ping on standby

[wangdu]

Hello experts,

I have an issue...at a site the standby cpu looses ping occasionally. Means to say if we ping stanby IP address on certain occasions it gives request time out and again starts giving proper reply. This goes on and on throughout the day. No issue with main cpu ip address and role address only issue with standby.
Have checked the cables, connections via RMA to cpu and nothing seems to be working out.
Please help.
R8.0.1-g1.503-c7s2
Thank You,
Wangdu
