Mounting via nfs cluster ip was failing and netstat ouput showed a connection in SYN_SENT state to the cluster IP.

Issue

• Mounting via nfs cluster ip was failing and netstat ouput showed a connection in SYN_SENT state to the cluster IP.

• When issue was reported the connection is still there in SYN_SENT after few days.

• Is this connection ever going to terminate/timeout?

$ netstat -an | grep .112
tcp        0      1 x.x.x.x:816         y.y.y.y:2049        SYN_SENT

[1] Please advise:

• Is this a bug?
• Will SYN_SENT terminate itself?
• If not, how can we resolve?
• How can we prevent it from happening again.
