Is there any way to disable, manually flush, or change the timeout settings of

no such interface exists. A workaround could be to overflow the
DRC with dummy requests from another unrelated client.
The size of the UDP DRC is 1024.

My problem is I use NFS on a lot of constantly rebooting NFS clients and these 
clients have no decent random number generator to seed the RPC transaction id. 
(They are embedded systems)  As a result, they all use the exact same XID and 
when they reboot they get the same IP from DHCP.  As a result, the 
non-idempotent requests are not performed correctly since the server responds 
with the response it gave from the board's last bootup.
