[gpfsug-discuss] gpfs rdma expels

Hi UG list,
We have a large rdma/tcp multi-cluster gpfs filesystem, about 2/3 of 
clients use RDMA. We see a large number of expels of rdma clients but 
less of the tcp clients.
Most of the gpfs config is at defaults. We are unclear if any of the 
non-RDMA config items (eg. Idle socket timeout) would help our issue. 
Any suggestions on gpfs config parameters we should investigate ?

thank-you in advance,
chris hunter
