When I have a user who has a large group membership, the following errors appear, and the "cd" command hangs. Sep 5 14:50:04 srv043 rpc.mountd[2563]: qword_eol: fflush failed: errno 22 (Invalid argument) Process : root 2563 1 0 14:44 ? 00:00:00 rpc.mountd -g The use of 60 groups is working well, but we have some users with more than 100 groups, and those fails. For uid mapping we use Winbind. /etc/exports : /export server.company.com(rw,no_subtree_check,no_root_squash) Client fstab : server.company.com:/export /data nfs nolock,defaults,user 1 2 Can anyone tell me what this error means ? Greetings .. Richard Smits
