Hi Anush, This is how I see the error. I added myself into more than 16 posix groups and I start seeing the "Transport endpoint is not connected" error, and could no longer access the gluster file system anymore. I have no problem when using another user (tstopr) that belongs to less than 16 posix groups. Both server and client machines are running RHEL5.8, kernel version 2.6.18-308.1.1, and glusterfs 3.3.0beta3-1 . Under 3.2.6-1, I could at least see the file system content as both users. Of couse I have problem with group permissions because of the rpc 16 gid limit.
