Description

when we enable message dropping on routers, and run a simple MPI program to repeat fstat and fchmod, I saw a lot of warnings like this in log:

Lustre: 17660:0:(client.c:304:ptlrpc_at_adj_net_latency()) Reported service time 7 > total measured time 0
Lustre: 17663:0:(client.c:304:ptlrpc_at_adj_net_latency()) Reported service time 7 > total measured time 0

they may be harmless, but it's better to fix them.
