Well, one thing to remember is that all TCPIP communications in UNIX is via the File System calls. So things like SYSLOGDn will be waiting in a FILE SYS KERNEL WAIT when it is waiting for something to send it a message to log. So a FILE SYS KERNEL WAIT does not mean DISK I/O wait or anything like that. It could mean waiting for TCPIP input or input via a PIPE (either unnamed or a FIFO). So, in and of itself, it does not mean you have a problem. -- John McKown Senior Systems Programmer HealthMarkets Keeping the Promise of Affordable Coverage Administrative Services Group Information Technology The information contained in this e-mail message may be privileged and/or confidential.
