Could apache be mmapping binary files? If for some odd reason it was
doing mmap with MAP_SHARED, the mmap would fail. That's the only
thing that comes to mind. Are there error messages in the apache
logs? You may have to strace apache to figure out if mmap is being
used...
Are you able to copy the jpg images off the pvfs volume with cp?

I'm just wondering if anyone else has seen this. I can get to text/
html content just fine if I serve files (or php for that matter)
off of the pvfs2 filesystem. But images are another thing. They
all stop after 0 bytes are sent. It is so strange.
Any thoughts? I've ***'d out the IP address/domain here...
