NFS blocked

["Damien \"zaide\"" <list@zaide.org>]

I have a strange problem on my nfsv3 all work fine but when i try to cat 
a file inside a mounted nfs partition who work with apache's session i 
get this problem:

$ strace cat /web/tmp/sess_231f9a00283f90be0ddd9a19e583f492
execve("/bin/cat", ["cat", 
"/web/tmp/sess_231f9a00283f90be0ddd9a19e583f492"], [/* 18 vars */]) = 0
....
open("/web/tmp/sess_231f9a00283f90be0ddd9a19e583f492", 
O_RDONLY|O_LARGEFILE) = 3
fstat64(3, {st_mode=S_IFREG|0600, st_size=13, ...}) = 0
read(3, "cmp|i:0;", 32768)         = 13
write(1, "cmp|i:0;", 13cmp|i:0;)           = 13
read(3, "", 32768)                      = 0
brk(0)                                  = 0x8073000
brk(0)                                  = 0x8073000
brk(0x8072000)                          = 0x8072000
brk(0)                                  = 0x8072000
close(3

and that all, it is blocked to the close() function.

my process:
test-cl   8678  0.0  0.0  1724  564 pts/4    S+   10:52   0:00 strace 
cat /web/tmp/sess_231f9a00283f90be0ddd9a19e583f492
test-cl  19613  0.0  0.0  1824  432 pts/4    D+   10:52   0:00 cat 
/web/tmp/sess_231f9a00283f90be0ddd9a19e583f492

my mounted partitions:
nfsserver:/data1/web/tmp on /web/tmp type nfs 
(rw,noexec,nosuid,addr=172.16.8.100)

and in my log:
Feb  9 11:24:35 nfs-client kernel: lockd: server 172.16.8.100 not 
responding, still trying

that all i have, so do you have any solutions, do you have allready seen 
this?
