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
