Three ISP and gateway temporarily unreachable

[mokhovikov]

Hello,

I have a 2801 with HWIC-4ESW and three isp connection with tracking, sla etc. (read config)

ISP1 and ISP2 links works fine, but ISP3 every 1-2 min cannot ping gateway and track state go "DOWN" state. After that i try ping gateway from vlan3:

#ping ISP3_GW

..!!!!!!!

and track goes "UP", and this only possible what track go UP(when ping ISP3_IP from WAN, ISP3_IP not reply).

I try delete all additional options(track,nat,route-map..) from config and configure ISP3 on other interface(fa0/0), but have same result..

Only this ISP3 link go through converter to fiber, but with workstation PC this ISP3 link works normally.
