Thanks very much Trond. Thanks for the testing! So this was with the following three patches applied on the server on top of 2.6.26? [PATCH 1/3] SUNRPC: Ensure the server closes sockets in a timely fashion [PATCH 2/3] SUNRPC: We only need to call svc_delete_xprt() once... [PATCH 3/3] SUNRPC: svc_xprt_enqueue should not refuse to enqueue 'XPT_DEAD' transports I'll try to take a look at these before I leave for the holidays, assuming the versions Trond posted on Nov. 30 are the latest. --b. -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
