Hi, what is the harm of sending more than one MON request for a peer?
Maybe no harm.
The rpc.statd won't record the peer twice.
I found this when I tested the xfstest generic/089.
The rpc task for that msg sometimes take very long time.
rpc took 57 sec who t_mtab/2377 srv rpc.statd xid 2453489031 prog statd/100024/1 proc 2 prot 6 flags 0x680
MON is supposed to be a call to a local service (on the same host).
It would be interesting if you could determine why it takes so long.
Yes, I'm working for that.
I think this is an optimization point.
Why do we have to send multiple requests?
I think the msg just send only one time is enough.
RPC and rpc.statd maybe consume for a long time on the network.
