Wow, that was fast. Yes, its all on Netapp disk or NFS. Infact I have a whole bunch of servers
running off of that Netapp, and only one apache instance thats giving me trouble. I will look
into this enablemmap & enablesendfile option.

Thanks very much.

Is your document root or where the script is running from a NFS mount?
MMAP and SendFile don't play well with NFS and cause segfaults.
