It really depends on the program, but I'd guess that it saw something
in the fstat64() call that it didn't like. You might want to use strace

returned by the fstat64 call.
With the working kernel:
access("/mnt/isilon/fonts/arial.ttf", R_OK) = 0
open("/mnt/isilon/fonts/arial.ttf", O_RDONLY) = 3
fcntl64(3, F_SETFD, FD_CLOEXEC) = 0
fstat64(3, {st_dev=makedev(0, 25), st_ino=4634215,
st_mode=S_IFREG|0666, st_nlink=1, st_uid=1001, st_gid=100,
st_blksize=32768, st_blocks=194, st_size=48784,
st_atime=2008/05/14-11:46:53, st_mtime=2008/05/14-11:46:53,
st_ctime=2008/05/14-21:12:18}) = 0
mmap2(NULL, 48784, PROT_READ, MAP_PRIVATE, 3, 0) = 0xb7a07000
close(3)
With the *non* working kernel:
access("/mnt/isilon/fonts/arial.ttf", R_OK) = 0
open("/mnt/isilon/fonts/arial.ttf", O_RDONLY) = 3
fcntl64(3, F_SETFD, FD_CLOEXEC) = 0
fstat64(3, {st_dev=makedev(0, 23), st_ino=4299601510,
st_mode=S_IFREG|0666, st_nlink=1, st_uid=1001, st_gid=100,
st_blksize=32768, st_blocks=194, st_size=48784,
st_atime=2008/05/14-11:46:53, st_mtime=2008/05/14-11:46:53,
st_ctime=2008/05/14-21:12:18}) = 0
close(3) = 0
Still looks almost identical, except the missing mmap2 in the
non-working kernel. Also, the st_ino is different... should they be
the same?
Is this a 32 bit app running on a 64 OS by any chance?
