CentOS - Jan 2013 - Is this a NFSv4 bug??

HI all,

 I have configured a CentOS 6.3 x86_64 as a NFSv4 server and I am
suffering errors like this:

 perl[7889]: segfault at a80 ip 00007fb870227ea2 sp 00007fff2fecda30
error 4 in libperl.so[7fb870193000+162000]

The symptoms are the same as described in this thread:

http://serverfault.com/questions/235059/vfs-file-max-limit-1231582-reached

 Can anyone confirm that is a bug when NFSv4 is used?

My actual options are:

fs.file-max = 1639200

[root at server01 fs]# lsof |wc -l
3962

[root at server01 fs]# cat file-nr
3040    0       1639200

We tested 6.x and NFSv4 - other than speed (much slower than v3, unless
you use async), we saw no perl problems.
