If a reply is not received from the server within the RPC timeout period, the request is retransmitted subject to the timeout and retransmission parameters for that mount point. weblink

Thus, if a process attempts, for example, a write to a remote server and that server is unreachable, the user's application hangs and the user can't do anything to abort the Red Hat may request a vmcore from an NFS Client or NFS Server at a later date if it is believed there is a specific bug within RHEL, but a vmcore Ultimate Australian Canal Are people of Nordic Nations "happier, healthier" with "a higher standard of living overall than Americans"?

If your network connection to the server is flaky or goes through a loaded router, you may either increase the initial timeout using the timeo option or hard-mount the volumes. Nfs Timeo Because certain NFS operations take longer to complete than others, Solaris uses three different values for the minimum (and initial) timeout of the various NFS operations. The numbers in parentheses are the actual times in milliseconds; the other values are unscaled values kept by the kernel and can be ignored.

badxid is incremented each time a duplicate reply is received for a retransmitted request (an RPC request retains its XID through all retransmission cycles).
