The process appears to hang in the call to close. Output from the ps command shows the process has gone into the uninterruptible IO state and the systems cpu usage goes to zero. The process stays this way until the system is rebooted. Any ideas whats going on here? Please CC me personally with any replies. thanks tim -- To unsubscribe from this list: send the line "unsubscribe linux-newbie" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.linux-learn.org/faqs
