Hi there, I get a (rather odd) repeatable bug; if I have a file with permissions -rw-r--r-- (644), and edit it using "vi", I get: E297: Write error in swap file E207: Can't delete backup file E138: Can't write viminfo file /home/scmijg/.viminfo! Next thing you know, glusterfs has core dumped. I've run it in non-daemon mode, and "DEBUG" level - no messages, apart from along the lines of "glibc detected" and "free(): invalid next size (fast)" I dropped the core into gdb, ran a backtrace and it listed "unify_getxattr_cbk" in "unify.so" as the culprit. Looks like pointer corruption? The config is 4 hosts, all hosting their local HDs apart from 1 machine which is hosting an external (USB) drive in addition. Everything running RHEL, all machines AMD Opteron dual-core... Anyone else had this trouble? Otherwise, with other access, Gluster seems OK... Very odd. Say, using "vi" with a file permissions of "-rwxr-xr-x" works fine... Thanks for any help! Ian
