MPLS -vs- Frame Relay and Checksum eerrors

[sfwi]

I have a set of servers which seem to be generating checksum challanged packets and one is on Frame Relay and the rest are on MPLS. The Frame Relay server seems to communicate better with the host than the MPLS one does.

Heres the question, IS MPLS even aware of the contents of the data burden in the packet (L5 thru L7)? Could it be macking a judgement call on the content and dropping the packet?

well in theory they shouldn't.
but weve recently had a customer whos traffic is being affected by the mpls policy on an edge router... it is somehow causeing erratic latency behaviors to encrypted traffic.
all traffic that is not in the tunnel is fine though...
