Due to a Red Hat 3.0 update 3 anomaly, Adaptive Server Enterprise occasionally stops responding when kernel asynchronous I/O is enabled. When this happens, Adaptive Server Enterprise generally displays a high CPU load—approximately 99%—without I/O. Adaptive Server Enterprise can still accept connections, but cannot recover; you must restart the system to clear the process.
This problem has been reported to Red Hat and addressed in kernel 2.4.21-27.6.EL.
For more information, see the Red Hat Web site.
