Unfortunately not, and no messages like that in any of the clients, deadlocked or no. From an IO perspective, the NFS servers have capacity and bandwidth to spare. We haven't been able to see any load-related causes to this, although that's not to say they're not there. We *have* seen this problem under a lighter load, with just 4-8 servers running the same 8 processes per server, but that's quite rare, I suspect just due to the rarity of the problem. This happens over both GigE or IPoIB (QDR) as well. -- 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
