Subject: rdma connection close/reopen every 5 mins
Date: Wed, 26 Apr 2017 10:23:40 -0700	[thread overview]
Message-ID: <odql2m$vup$1@blaine.gmane.org> (raw)

Hello, I have setup NFS/RDMA on our infiniband network.  The OS is 
CentOS 6.8 with kernel 2.6.32-696.1.1.el6.x86_64 and I am using 
rdma/nfs-rdma packages from the OS version 6.9_4.1.  The connection is 
successful:

10.10.11.249:/newwing on /newwing type nfs 
(rw,rdma,port=20049,addr=10.10.11.249)

except in /var/log/messages I am always seeing this exactly every 5 minutes:
  kernel: rpcrdma: connection to 10.10.11.249:20049 closed (-103)
  kernel: rpcrdma: connection to 10.10.11.249:20049 on mlx4_0, memreg 6 
slots 32 ird 16

I suppose it is from some service or cron job.... But I wonder how I 
could keep the connection open so this isn't happening every 5 minutes?

Thanks
