[NFS-Ganesha-Support] proxy fails to renew session

Version : 2.8.3 FSAL: PROXY NFS version tried : 4.1 and 4.2 Setup: Running iozone from 40 hosts Proxy works fine under low load ( 10 threads of iozone). As loaded increases, proxy server fails with only message after few seconds: Failed to renew session Any idea? I am planning to use a proxy in production. Can proxy take the load? I see that the connection between proxy server and nfs server is just one which will have limited RPC slots ( 16 by default ) per host. Can 16 RPC take a reasonable amount of load for production use? -alok
