Problem with router Cisco 1700 and HP J4900A ProCurve Switch 2626

[dnnn]

Hi, first of all, sorry for my inglish :)
I have two router Cisco 1700 with HSRP and load balancing enabled, and 3 HP J4900A ProCurve 2626 switches, each router Cisco is pluged to a diferent swicth.
Problem is that sometimes it starts lossing packets. When i do pings to the lan ip of booth routers i also losse packets, even if i am doing ping in the same network where the routers are. The only way to get things work again is rebooting the switches.

any ideas of whats going on? or possible things to check?

Hi,
First of all you mentioned that you 2 routers & 3 switches..each router us pluged to switch.... right...

Input packet errors are caused due to mismatch in the speed/duplex settings on the server and switch side.
The best way to avoid packet errors is to set the NIC setting and the switch settings to auto-negotiate ON.

Thanks & Regards
