      A client was running "rm" to remove a couple of million files when MDS system load shot to 30 and kernel trace dumping complaining hung tasks - See attached output from "dmesg"

      I would think this is normal workload for a duo-westmere CPU / 24GB RAM bonded myricom 10Gbps system.

      We have been seeing happening more frequently in 2.4.3 than when we were at 1.8.7.

      Anything suggestion?

      thanks,
      Haisong
