Dear all, I have a similar issue, but I am running a 2.6.38-6 kernel on a HPC cluster, and I had this issue quite often lately, especially on jobs accessing the network (but since we are using NFS and MPI, many jobs are actually accessing the network). I'm using an SMP, non-PREEMPT kernel (2cpu*8 cores each machine). I can provide you more information if you need, but please reply to me since I'm not subscribed to the mailing list. .a. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
