Last updated on AUGUST 15, 2017

Applies to:

Solaris Operating System - Version 10 3/05 and later
Information in this document applies to any platform.

Various issues due to failing NFS TCP connections, shortly after some file transfers are initiated.

Packet traces show packets leaving the NFS client and not reaching the NFS server.

The issue is only present when a Juniper firewall is in the mix, and only when the Juniper TCP sequence check feature is enabled.
