Some things to try... 1. Upgrade the kernel to the latest errata version (yours is out of date). These types of things are sometimes driver/kernel related. (You really should do this one. The 2.4.7 kernel was a dog for me.) 2. Try using asynchronous writes to the log files (recommended for performance overall). You can do this by putting a dash "-" (no quotes) in front of the log file in the syslogd.conf file. For example : *.info -/var/log/info.messages 3. Check to make sure you aren't running out of file descriptors. Modify if needed. 4. Try using a different NIC. Again the driver possibility. Hope that helps. -- Brian Ashe CTO Dee-Web Software Services, LLC.
